获取所有sections
print(config.sections())
['server', 'system', 'client']

获取指定 section 的 keys & values
print(config.items('system'))
[('server', '45'), ('compression', 'yes'), ('market64', 'xiadan1.exe'), ('market128', 'xiadan2.exe'), ('market256', 'xiadan3.exe')]  # 注意items()返回的字符串会全变成小写

获取指定 section 的 keys
print(config.options('system'))
['market64', 'market128', 'market256', 'server', 'compression'] #会打印default中的keys

获取指定 key 的 value
print(config['system']['market64'])
xiadan1.exe
