alguém sabe me dizer o que esta errado com esse programa ? :( :unsure:

[Kakao]

Eu ajeitei o programa. Veja linhas 1, 27 e 53. Parece que você está lendo o arquivo byte a byte por uma exigência de algum curso, o que é normal para exercitar algoritmos. Mas se não for isso ler um arquivo texto linha a linha é muito mais simples e evita as muitas armadilhas do byte a byte.

Qual a vantagem neste caso de se usar __getitem__()? Eu troquei pela indexação simples [].

import sys

def converteMega(byte):
    return float(byte)/pow(1024,2)

def percentualUso(valor_parcial, total):
    return float(valor_parcial)*100/float(total)

f = open('usuarios.txt','r')

bloco = f.read()
i = 0
soma = 0
quantidade = 0
media = 0

x = 0
nomes = []
espacos = []
string = ''

while True:

   snumero = ''
   snome = ''

   if (i) == len(bloco):
       media = soma/quantidade
      
       while x < len(espacos):
           perc = '%10.2f' % percentualUso( converteMega(espacos[x]), soma ) + ' %'
           no = nomes[x]
           esp = '%10.2f MB' % converteMega( espacos[x] )
           string =  str(x+1) + '\t' + no + '\t' + str(esp) + '\t' + str(perc)
           print string
           x += 1

       so = 'Espaco total ocupado: %.2f MB' % soma
       me = 'Espaco medio ocupado: %.2f MB' % media
       sys.exit(0)
  
   while bloco[i] != ' ':
       snome = snome + bloco[i]  
       i += 1

   while bloco[i] == ' ':  
       i += 1
      
   while bloco[i] != '\n':
       snumero = snumero + bloco[i]
       i += 1

usei __getitem__() sem conhecer ao certo as diferencas entre ele a indexacao simples. :) . então era por isso que esta dando aquele problema para saltar de linhas ? :unsure:

[Guest - MarcelComputacao -]

a proposito, para fazer o tratamento nesse arquivo, da forma como o resultado deve ser gerado, obrigatoriamente devo ler caracter por caracter correto ? :blink:

[Kakao]

Não. O problema de saltar linha era causado por um erro no algoritmo. Compare o seu programa com o programa que eu coloquei e veja a diferença (eu citei as linhas diferentes).

a proposito, para fazer o tratamento nesse arquivo, da forma como o resultado deve ser gerado, obrigatoriamente devo ler caracter por caracter correto ? :blink:

Não. Ler caracter por caracter é a pior solução. A melhor solução é ler linha a linha com f.readline(). E fica melhor ainda se os campos do arquivo estiverem separados por tab porque aí basta fazer linha.split('\t') para ter uma lista com todos os campos daquela linha.

[Guest - MarcelComputacao -]

Ler caracter por caracter é a pior solução. A melhor solução é ler linha a linha com f.readline().

mas ler linha por linha implica em varias operacoes de i/o. Isto representa um custo muito grande se o arquivo tiver dois milhoes de tuplas, por exemplo. Neste caso, teremos que fazer 2.000.000 de acessos ao arquivo. Enquanto que ao usar f.read(), acessaremos o arquivo somente uma vez e os dados ficarao na memoria ram a partir desse momento, que é mais rapida do que a memoria secundaria. Por isso, ainda estou convencido de que com f.read() o desempenho é melhor. ;)

[Guest - MarcelComputacao -]

:D estou muito feliz com esse forum ;) . você tem se mostrado uma pessoa muito sabia e educada. :D

[Kakao]

Não são dois milhões de acessos ao arquivo. São tantos quantos o tamanho do buffer de leitura determinar. Aliás o tamanho do buffer é o terceiro parâmetro que pode ser passado para a função open(). Se omitido, o tamanho é o default do sistema. Se você passar um tamanho razoável, digamos 10 ou 100 mil bytes, o desempenho será muito bom.

Enquanto que ao usar f.read(), acessaremos o arquivo somente uma vez e os dados ficarao na memoria ram a partir desse momento, que é mais rapida do que a memoria secundaria. Por isso, ainda estou convencido de que com f.read() o desempenho é melhor. ;)

Não faça isso com um arquivo grande. Se o arquivo tiver um tamanho parecido ou maior que a memória disponível o sistema vai usar memória virtual e o desempenho vai despencar.

A otimização prematura é a raiz de muitos problemas em programação. Não otimize a não ser que você consiga provar com testes que a otimização vai ser importante. A otimização torna o seu código quebradiço e obscuro e geralmente não vale a pena. Este é um dos mandamentos da boa prática de programação e quem já passou sufocos aprendeu a respeitar.

O erro de algoritmo do seu código, difícil de achar, foi exatamente por quebrar esta regra. Isto com um programa de poucas linhas. Imagine quando voce estiver envolvido com um sistema de milhares ou dezenas de milhares de linhas. Escreva códigos simples e claros. Deixe a esperteza para as horas certas.

[Guest - MarcelComputacao -]

é possivel aumentar o desempenho desse programa, caso o arquivo de entrada seja maior ? :unsure: usando threads ? :) tem alguma ideia de como eu poderia fazer isso ? :blink:

[Guest - MarcelComputacao -]

qual seria a melhor forma de ordenar os dados pelo campo que contem o percentual para depois colocar os registros ordenados no arquivo ? :)

[Kakao]

Dado este arquivo com os campos separados por tab:

alexandre    456123789
anderson    1245698456
antonio    123456456
carlos    91257581
cesar    987458
rosemary    789456125

Eu faria assim:

espaco_ocupado_total = 0
lista = []
MB = 1024 * 1024

f = open('usuarios_tab.txt', 'r')
for linha in f:
   lista.append(linha.rstrip().split('\t'))
   lista[-1][1] = float(lista[-1][1])
   espaco_ocupado_total += lista[-1][1]
f.close()

lista.sort(None,key=lambda l: l[1])
for linha in lista:
   print '%s\t%.2f\t%.2f' % (
      linha[0],
      linha[1] / MB,
      100 * linha[1] / espaco_ocupado_total
      )

[MarcelComputacao]

como faco para gerar o resultado desse programa em um pagina html ? :blink:

[Kakao]

Duas das muitas alternativas são usar CGI ou mod_python. Se você lê ou adivinha ou pouco de inglês consulte o meu tutorial: http://webpython.codepoint.net

Também deve existir muita coisa em português no site do python Brasil.

Tente fazer alguma coisa. Se não der certo poste aqui o que você tentou que a gente ajuda.

[MarcelComputacao]

estou tentando usar o mod_python e quando eu testo o programa:

def index():
   s = """\
<html>
<body>
<h2>Hello World!</h2>
</body>
</html>
"""
   return s

ocorre o seguinte erro no navegador: :(

def index(): s = """\ 
Hello World!
""" return s

estou testando assim:

http://localhost/inc/paginas/python/hello.py

o que esta errado com meu teste ? :unsure:

[Kakao]

Mostre a configuração do Apache.

[MarcelComputacao]

olá kakao,

a configuracao do arquivo httpd.conf é a seguinte:

#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs-2.0/> for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# The configuration directives are grouped into three basic sections:
#  1. Directives that control the operation of the Apache server process as a
#     whole (the 'global environment').
#  2. Directives that define the parameters of the 'main' or 'default' server,
#     which responds to requests that aren't handled by a virtual host.
#     These directives also provide default values for the settings
#     of all virtual hosts.
#  3. Settings for virtual hosts, which allow Web requests to be sent to
#     different IP addresses or hostnames and have them handled by the
#     same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
# with ServerRoot set to "C:/Program Files/Apache Group/Apache2" will be interpreted by the
# server as "C:/Program Files/Apache Group/Apache2/logs/foo.log".
#
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which Apache.exe is located
# will be used by default.  It is recommended that you always supply
# an explicit drive letter in absolute paths, however, to avoid
# confusion.
#
Include conf/vertrigo.conf 
### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE!  If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.0/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#


#
# ScoreBoardFile: File used to store internal server process information.
# If unspecified (the default), the scoreboard will be stored in an
# anonymous shared memory segment, and will be unavailable to third-party
# applications.
# If specified, ensure that no two invocations of Apache share the same
# scoreboard file. The scoreboard file MUST BE STORED ON A LOCAL DISK.
#
#ScoreBoardFile logs/apache_runtime_status

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
#
PidFile logs/httpd.pid

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 15

##
## Server-Pool Size Regulation (MPM specific)
## 

# WinNT MPM
# ThreadsPerChild: constant number of worker threads in the server process
# MaxRequestsPerChild: maximum  number of requests a server process serves
<IfModule mpm_winnt.c>
ThreadsPerChild 250
MaxRequestsPerChild  0
</IfModule>

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
#Listen 12.34.56.78:80
Listen 80

# Dynamic Shared Object (DSO) Support

# ExtendedStatus controls whether Apache will generate "full" status
# information (ExtendedStatus On) or just basic information (ExtendedStatus
# Off) when the "server-status" handler is called. The default is Off.
#
#ExtendedStatus On

### Section 2: 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition.  These values also provide defaults for
# any <VirtualHost> containers you may define later in the file.
#
# All of these directives may appear inside <VirtualHost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#

#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
ServerAdmin root@localhost

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If this is not set to valid DNS name for your host, server-generated
# redirections will not work.  See also the UseCanonicalName directive.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
# You will have to access it by its address anyway, and this will make 
# redirections work in a sensible way.
#
ServerName VertrigoServ:80

#
# UseCanonicalName: Determines how Apache constructs self-referencing 
# URLs and the SERVER_NAME and SERVER_PORT variables.
# When set "Off", Apache will use the Hostname and Port supplied
# by the client.  When set "On", Apache will use the value of the
# ServerName directive.
#
UseCanonicalName Off

#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#


#
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that

# Alias fakename realname
#
# Note that if you include a trailing / on fakename then the server will
# require it to be present in the URL.  So "/icons" isn't aliased in this
# example, only "/icons/".  If the fakename is slash-terminated, then the 
# realname must also be slash terminated, and if the fakename omits the 
# trailing slash, the realname must also omit it.
#
# We include the /icons/ alias for FancyIndexed directory listings.  If you
# do not use FancyIndexing, you may comment this out.
#

# In vertrigo.conf

#
# This should be changed to the ServerRoot/manual/.  The alias provides
# the manual, even if you choose to move your DocumentRoot.  You may comment
# this out if you do not care for the documentation.
#
#AliasMatch ^/manual(?:/(?:De|en|es|fr|já|ko|ru))?(/.*)?$ "C:/Program Files/Apache Group/Apache2/manual$1"

#<Directory "C:/Program Files/Apache Group/Apache2/manual">

#    RedirectMatch 301 ^/manual(?:/(de|en|es|fr|já|ko|ru)){2,}(/.*)?$ /manual/$1$2
#</Directory>

#
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the realname directory are treated as applications and
# run by the server when requested rather than as documents sent to the client.
# The same rules about trailing "/" apply to ScriptAlias directives as to
# Alias.
#
#ScriptAlias /cgi-bin/ "C:/Program Files/Apache Group/Apache2/cgi-bin/"

#
# "C:/Program Files/Apache Group/Apache2/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.
#
#<Directory "C:/Program Files/Apache Group/Apache2/cgi-bin">
#    AllowOverride None
#    Options None

#
# Redirect allows you to tell clients about documents which used to exist in
# your server's namespace, but do not anymore. This allows you to tell the
# clients where to look for the relocated document.
# Example:
# Redirect permanent /foo [url=http://www.example.com/bar]http://www.example.com/bar[/url]

# AddType allows you to add to or override the MIME configuration
# file mime.types for specific file types.
#
#AddType application/x-tar .tgz
#
# AddEncoding allows you to have certain browsers (Mosaic/X 2.1+) uncompress
# information on the fly. Note: Not all browsers support this.
# Despite the name similarity, the following Add* directives have nothing
# to do with the FancyIndexing customization directives above.
#
#AddEncoding x-compress .Z
#AddEncoding x-gzip .gz .tgz
#
# If the AddEncoding directives above are commented-out, then you
# probably should define those extensions to indicate media types:
#
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz

#
# AddHandler allows you to map certain file extensions to "handlers":
# actions unrelated to filetype. These can be either built into the server
# or added with the Action directive (see below)
#
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#
#AddHandler cgi-script .cgi

#
# For files that include their own HTTP headers:
#
#AddHandler send-as-is asis

#
# For server-parsed imagemap files:
#
#AddHandler imap-file map

#
# For type maps (negotiated resources):
# (This is enabled by default to allow the Apache "It Worked" page
#  to be distributed in multiple languages.)
#
AddHandler type-map var

#
# Filters allow you to process content before it is sent to the client.
#
# To parse .shtml files for server-side includes (SSI):
# (You will also need to add "Includes" to the "Options" directive.)
#
#AddType text/html .shtml
#AddOutputFilter INCLUDES .shtml

#
# Action lets you define media types that will execute a script whenever
# a matching file is called. This eliminates the need for repeated URL
# pathnames for oft-used CGI file processors.
# Format: Action media/type /cgi-script/location
# Format: Action handler-name /cgi-script/location

#
# Customizable error responses come in three flavors:
# 1) plain text 2) local redirects 3) external redirects
#
# Some examples:
#ErrorDocument 500 "The server made a boo boo."
#ErrorDocument 404 /missing.html
#ErrorDocument 404 "/cgi-bin/missing_handler.pl"
#ErrorDocument 402 [url=http://www.example.com/subscription_info.html]http://www.example.com/subscription_info.html[/url]
#

#
# Putting this all together, we can internationalize error responses.
#
# We use Alias to redirect any /error/HTTP_<error>.html.var response to
# our collection of by-error message multi-language collections.  We use 
# includes to substitute the appropriate text.
#
# You can modify the messages' appearance without changing any of the
# default HTTP_<error>.html.var files by adding the line:
#
#   Alias /error/include/ "/your/include/path/"
#
# which allows you to create your own set of files by starting with the
# @exp_errordir@/include/ files and copying them to /your/include/path/, 
# even on a per-VirtualHost basis.  The default include files will display
# your Apache version number and your ServerAdmin email address regardless
# of the setting of ServerSignature.
#
# The internationalized error documents require mod_alias, mod_include
# and mod_negotiation.  To activate them, uncomment the following 30 lines.

#    Alias /error/ "@exp_errordir@/"
#
#    <Directory "@exp_errordir@">

### Section 3: Virtual Hosts
#
# VirtualHost: If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs-2.0/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# Use name-based virtual hosting.
#
#NameVirtualHost *:80

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for requests without a known
# server name.
#
#<VirtualHost *:80>
#    ServerAdmin webmaster@dummy-host.example.com
#    DocumentRoot /www/docs/dummy-host.example.com
#    ServerName dummy-host.example.com
#    ErrorLog logs/dummy-host.example.com-error_log
#    CustomLog logs/dummy-host.example.com-access_log common
#</VirtualHost>

[Kakao]

Baixe e instale o mod_python daqui:

http://httpd.apache.org/modules/python-download.cgi

Adicione esta linha ao httpd.conf:

LoadModule python_module modules/mod_python.so

O caminho deve apontar para o diretório onde está o módulo a ser executado. De preferência um diretório dentro de htdocs. Eu testei no Windows porque provavelmente é o que você está usando:

<Directory "c:/arquivos de programas/xampp/htdocs/python">
   SetHandler mod_python
   PythonHandler mod_python.publisher
   PythonDebug On
</Directory>

[MarcelComputacao]

fiz conforme voce sugeri kakao. Até instalei o xampp, mas agora está dando o erro abaixo quando eu executo da seguinte forma: http://localhost/xampp/python/. :(

Objeto não encontrado!

A URL requisitada não foi encontrada neste servidor. Se você digitou o endereço (URL) manualmente, por favor verifique novamente a sintaxe do endereço.

Se você acredita ter encontrado um problema no servidor, por favor entre em contato com o webmaster.

Apache/2.2.3 (Win32) DAV/2 mod_ssl/2.2.3 OpenSSL/0.9.8d mod_autoindex_color PHP/5.2.0

o que pode ser isso ?

[Kakao]

fiz conforme voce sugeri kakao. Até instalei o xampp, mas agora está dando o erro abaixo quando eu executo da seguinte forma: http://localhost/xampp/python/. :(

Ele só vai encontrar algo neste endereço se o nome do programa for index.py. Se não for você tem que passar o nome do programa:

http://localhost/xampp/python/meu_programa

[MarcelComputacao]

ontem eu havia tentado tambem passando conforme você sugeriu agora, mas o erro era o mesmo. :(

Desculpe-me, mas tambem ocorreu um outro erro agora, com o xampp. Quando eu inicializo o xampp, eu coloquei para iniciar o apache como servico automaticamente, mas o apache não quer iniciar. Quando eu mando restartar o apache então ele fala que ocorreu um erro na linha 142 do arquivo httpd.conf e diz que não pode carregar o arquivo mod_python.so no servidor :(

eu fiz a instalacao do mod_python que voce falou e ao final da instalacao mandei carregar o mod_python no apache do diretorio xampp

[Kakao]

Se o diretório Python é:

"c:/arquivos de programas/xampp/htdocs/python"

Então o endereço web vai ser:

httpd://localhost/python/meu_programa.

É mais fácil se o diretório Python estiver em htdocs, caso contrário é necessário mudar a configuração do Apache.

Veja qual é a linha 142 e poste aqui.

[MarcelComputacao]

a linha 142 é essa aí:

LoadModule python_module modules/mod_python.so

[Kakao]

Veja se existe o arquivo mod_python.so em

C:\arquivos de programas\xampp\apache\modules

Se não existir instale de novo o mod_python

[MarcelComputacao]

esse arquivo existe nesse local.

achei o seguinte documento na Internet:

http://www.modpython.org/live/current/doc-...acheconfig.html

poderia ajudar ? :unsure:

[MarcelComputacao]

apaguei o xampp, ele tava me causando muitos problemas :angry: e então baixei e instalei o VertrigoServ e agora o apache está funcionando beleza :D . Mas quando mudo as configuracoes do arquivo httpd.conf para executar scripts do python, aí dá pau no servidor e ele nem funciona quando eu digito localhost no browser. Apaguei as linhas de configuracao do python do httpd.conf e o apache voltou a funcionar. O que pode estar acontecendo ? :(

[Kakao]

Existe uma versão de instalação do mod_python para cada versão do Apache. Se você mudou a versão do Apache quando instalou o XAMPP o mod_python não vai mais funcionar.

Para ver a versão do apache que está instalada abra uma janela DOS e:

C:\Documents and Settings\cpn>"C:\Arquivos de programas\xampp\apache\bin\httpd.exe" -v
Server version: Apache/2.2.3
Server built:   Aug 13 2006 19:16:43

Depois baixe e instale a versão do mod_python correspondente.
