Configuration file Authoring in Python Configparser

Used to generate and modify common configuration documents, the name of the current module is changed to Configparser in the Python 3.x version.

Here's a look at a lot of the common document formats for software

What if you want to use Python to generate a document like this?

importconfigparserconfig =configparser.ConfigParser()config["DEFAULT"] ={‘ServerAliveInterval‘: ‘45‘,                      ‘Compression‘: ‘yes‘,                     ‘CompressionLevel‘: ‘9‘}config[‘bitbucket.org‘] ={}config[‘bitbucket.org‘][‘User‘] =‘hg‘config[‘topsecret.server.com‘] ={}topsecret = config[‘topsecret.server.com‘]topsecret[‘Host Port‘] =‘50022‘# mutates the parsertopsecret[‘ForwardX11‘] =‘no‘# same hereconfig[‘DEFAULT‘][‘ForwardX11‘] =‘yes‘with open(‘example.ini‘, ‘w‘) as configfile:   config.write(configfile)

　　

When you're done, you can read it again.
