configparser模块

1. 配置文件格式

 1 [DEFALUT]
 2 compressionlevel = 9
 3 serveraliveinterval = 45
 4 compression = yes
 5 forwardx11 = yes
 6  
 7 [bitbucket.org]
 8 user = hg
 9  
10 [topsecret.server.com]
11 host port = 50022
12 forwardx11 = no

2. 生成配置文件

 1 # Python3
 2 import configparser
 3 
 4 # 创建对象
 5 config = configparser.ConfigParser()
 6 
 7 config["DEFAULT"] = {'ServerAliveInterval': '45',
 8                      'Compression': 'yes',
 9                      'CompressionLevel': '9'}
10 
11 # 第一个组
12 config['bitbucket.org'] = {}
13 config['bitbucket.org']['User'] = 'hg'
14 
15 # 第二个组
16 config['topsecret.server.com'] = {}
17 config['topsecret.server.com']
18 config['topsecret.server.com']['Host Port'] = '50022'  
19 config['topsecret.server.com']['ForwardX11'] = 'no'  
20 
21 # 配置DEFAULT
22 config['DEFAULT']['ForwardX11'] = 'yes'
23 
24 # 写入文件
25 with open('example.ini', 'w') as configfile:
26     config.write(configfile)

3. 配置文件操作

 1 import configparser
 2 
 3 conf = configparser.ConfigParser()
 4 # 读取配置文件
 5 conf.read("example.ini")
 6 
 7 print('-'*30)
 8 # 配置组
 9 print(conf.sections())
10 # 默认配置组
11 print(conf.defaults())
12 
13 print('-'*30)
14 # 判断组名是否存在
15 group_flag = 1 if 'bitbucket.org' in conf else 0
16 print(group_flag)
17 
18 print('-'*30)
19 # 取值
20 print(conf['bitbucket.org']['user'])
21 print(conf.get('bitbucket.org', 'user'))
22 
23 print('-'*30)
24 # 循环取值
25 for key in conf['bitbucket.org']:
26     print(key)
27 # 以列表的形式返回bitbucket.org组和默认组的key值
28 print(conf.options('bitbucket.org'))
29 # 以字典的形式返回bitbucket.org组和默认组的key，value值
30 print(conf.items('bitbucket.org'))
31 
32 print('-'*30)
33 # 删除section和option
34 conf.remove_section('bitbucket.org')
35 conf.remove_option('topsecret.server.com', 'forwardx11')
36 
37 # 判断是否有某个section
38 print(conf.has_section("test"))
39 # 添加section
40 conf.add_section("test")
41 
42 # 判断topsecret.server.com是否有ip值
43 print(conf.has_option("topsecret.server.com", "ip"))
44 # 设置ip值
45 conf.set("topsecret.server.com", "ip", "127.0.0.1")
46 
47 # 将修改重新写入文件
48 # 可以写入新文件
49 with open("example.ini", "w") as f:
50     conf.write(f)
