如何读取.cfg文件中的内容并将其解析到字典中？

import configparser

config = configparser.ConfigParser()
config.read('config.cfg')

config_dict = {}
for section in config.sections():
    config_dict[section] = {}
    for option in config.options(section):
        config_dict[section][option] = config.get(section, option)

[Section1]
key1 = value1
key2 = value2

[Section2]
key3 = value3
key4 = value4

{
    'Section1': {
        'key1': 'value1',
        'key2': 'value2'
    },
    'Section2': {
        'key3': 'value3',
        'key4': 'value4'
    }
}
