Python USES ConfigObj to read and write the implementation code for the configuration file

Find a simple and powerful, speaking, reading and writing configuration files lib, (link: http://www.voidspace.org.uk/python/configobj.html).
I think the biggest highlight is the built-in format validation, and support for complex nested formats, but also quite simple to use.

Let's do an example.
Read the file

from configobj import ConfigObj  
    config = ConfigObj(filename)  
    #  
    value1 = config['keyword1']  
    value2 = config['keyword2']  
    #  
    section1 = config['section1']  
    value3 = section1['keyword3']  
    value4 = section1['keyword4']  
    #  
    # you could also write  
    value3 = config['section1']['keyword3']  
    value4 = config['section1']['keyword4'] 

Write files

from configobj import ConfigObj  
    config = ConfigObj()  
    config.filename = filename  
    #  
    config['keyword1'] = value1  
    config['keyword2'] = value2  
    #  
    config['section1'] = {}  
    config['section1']['keyword3'] = value3  
    config['section1']['keyword4'] = value4  
    #  
    section2 = {  
        'keyword5': value5,  
        'keyword6': value6,  
        'sub-section': {  
            'keyword7': value7  
            }  
    }  
    config['section2'] = section2  
    #  
    config['section3'] = {}  
    config['section3']['keyword 8'] = [value8, value9, value10]  
    config['section3']['keyword 9'] = [value11, value12, value13]  
    #  
    config.write()
