6. Print data

print(config)

Output:

[
    {'key': 'global_parameter', 'sep': ' = ', 'value': 1}
],
{'section1':
    [
        {'key': '    option0', 'sep': ' = ', 'value': 0},
        {'key': '    option_without_value', 'sep': None, 'value': None},
        '    # This is comment for option1',
        {'key': '    option1', 'sep': ' = ', 'value': 100}
    ]
}

print(config['section1'])

Output:

[
    {'key': '    option0', 'sep': ' = ', 'value': 0},
    {'key': '    option_without_value', 'sep': None, 'value': None},
    '    # This is comment for option1',
    {'key': '    option1', 'sep': ' = ', 'value': 100}
]

Also you can use method to_text() for all config or for a section:

for line in config.to_text():
    print(line)

Output as text format:

global_parameter = 1
[section1] # this is comment
    option0 = 0
    option_without_value
    # This is comment for option1
    option1 = 100
