How to read and write INI file with Python3?

This can be something to start with:

import configparserconfig = configparser.ConfigParser()config.read('FILE.INI')print(config['DEFAULT']['path'])     # -> "/path/name/"config['DEFAULT']['path'] = '/var/shared/'    # updateconfig['DEFAULT']['default_message'] = 'Hey! help me!!'   # createwith open('FILE.INI', 'w') as configfile:    # save    config.write(configfile)

You can find more at the official configparser documentation.

Here's a complete read, update and write example.

Input file, test.ini

[section_a]string_val = hellobool_val = falseint_val = 11pi_val = 3.14

Working code.

try:    from configparser import ConfigParserexcept ImportError:    from ConfigParser import ConfigParser  # ver. < 3.0# instantiateconfig = ConfigParser()# parse existing fileconfig.read('test.ini')# read values from a sectionstring_val = config.get('section_a', 'string_val')bool_val = config.getboolean('section_a', 'bool_val')int_val = config.getint('section_a', 'int_val')float_val = config.getfloat('section_a', 'pi_val')# update existing valueconfig.set('section_a', 'string_val', 'world')# add a new section and some valuesconfig.add_section('section_b')config.set('section_b', 'meal_val', 'spam')config.set('section_b', 'not_found_val', '404')# save to a filewith open('test_update.ini', 'w') as configfile:    config.write(configfile)

Output file, test_update.ini

[section_a]string_val = worldbool_val = falseint_val = 11pi_val = 3.14[section_b]meal_val = spamnot_found_val = 404

The original input file remains untouched.

Python's standard library might be helpful in this case.
