The ConfigParser module reads configuration files.
The files should be written in a format similar to Windows INI files. The file contains one or more sections, separated by section names written in brackets. Each section can contain one or more configuration items.
Here’s the sample file used in Example 5-16:
[book] title: The Python Standard Library author: Fredrik Lundh email: [email protected] version: 2.0-001115 [ematter] pages: 250 [hardcopy] pages: 350
Example 5-16 uses the ConfigParser module to read the sample configuration file.
Example 5-16. Using the ConfigParser Module
File: configparser-example-1.py
import ConfigParser
import string
config = ConfigParser.ConfigParser()
config.read("samples/sample.ini")
# print summary
print
print string.upper(config.get("book", "title"))
print "by", config.get("book", "author"),
print "(" + config.get("book", "email") + ")"
print
print config.get("ematter", "pages"), "pages"
print
# dump entire config file
for section in config.sections():
print section
for option in config.options(section):
print " ", option, "=", config.get(section, option)

to a file, as Example 5-17 shows.
Example 5-17. Using the ConfigParser Module to Write Configuration Data
File: configparser-example-2.py
import ConfigParser
import sys
config = ConfigParser.ConfigParser()
# set a number of parameters
config.add_section("book")
config.set("book", "title", "the python standard library")
config.set("book", "author", "fredrik lundh")
config.add_section("ematter")
config.set("ematter", "pages", 250)
# write to screen
config.write(sys.stdout)
[book]
title = the python standard library
author = fredrik lundh
[ematter]
