17 topsecret = config['topsecret.server.com']
18 topsecret['Host Port'] = '50022'  # mutates the parser
19 topsecret['ForwardX11'] = 'no'  # same here
20 
21 config['DEFAULT']['ForwardX11'] = 'yes'
22 
23 with open('example.ini', 'w') as configfile: #创建，写
24     config.write(configfile)
25 
26 #读
27 config.read('example.ini')
28 print(config.sections()) #默认的不读出
29 print(config.defaults()) #有序字典
30 print('')
31 print(config['bitbucket.org']['User'])
32 print('')
33 for key in config['bitbucket.org']:
34     print(key) #本来只能输出　user键，但是默认的键也输出
35 print('')
36 config.remove_section('topsecret.server.com')
37 
38 print(config.has_section('topsecret.server.com')) #已被删，无法找到
39 
40 config.set('bitbucket.org','user','alex')#修改值
41 
42 config.write(open('i.cfg',"w"))#也可以写成同名文件example.ini，但那属于覆盖，不属于删除

执行结果：
