python模块--config

一、创建文件

 1 ##-----------------创建数据表--------------------------
 2 import configparser
 3 config = configparser.ConfigParser()
 4 
 5 config["DEFAULT"] = {
 6     'ServerAliveInterval': '45',
 7     'Compression': 'yes',
 8     'CompressionLevel': '9'
 9 }
10 
11 config["bitbucket.org"] = {}
12 config["bitbucket.org"]["user"] = "hg"
13 
14 config['topsecret.server.com'] = {}
15 topsecret = config['topsecret.server.com'] #  ?
16 topsecret['Host Post'] = '50022'  #mutates the parser
17 topsecret['ForwardX11'] = 'no' #same here
18 
19 with open('example.ini','w') as f:
20     config.write(f)

2、增删改查--查

 1 ###----------增删改查------------------------------
 2 import configparser
 3 config = configparser.ConfigParser()
 4 
 5 
 6 print(config.sections())  # 返回空列表[]
 7 # print(config.user())
 8 ##------------> 查
 9 config.read('example.ini')
10 print(config.sections())  #['bitbucket', 'topsecret.server.com']
11 
12 print('bytebong.com' in config)   #False
13 print(config['bitbucket.org']['user'])   # hg
14 
15 print(config['topsecret.server.com']['host post'])   #50022
16 print(config['topsecret.server.com']['forwardx11'])  #no
17 print(config['DEFAULT']['serveraliveinterval'])   #45
18 
19 for key in config['bitbucket.org']:
20     print('【bit】',key)
21 
22 print(config.options('bitbucket.org'))  # ??['user', 'serveraliveinterval', 'compression', 'compressionlevel']
23 print(config.items('bitbucket.org'))  #[('serveraliveinterval', '45'), ('compression', 'yes'), ('compressionlevel', '9'), ('user', 'hg')]
24 ##  下面的两组，不管取哪个，都会把[DEFAULT] 里面的顺带打印出来，这以后在实际中有相应的应用、
25 
26 print(config.get('bitbucket.org','compression'))   #?? yes

3、增、改、删

1 ##------> 删、改、增
2 config.add_section('zhao')   #  增加一条
3 config.set('zhao','key','python')
4 
5 config.remove_section('topsecret.server.com')
6 config.remove_option('bitbucket.org','user')
7 
8 config.write(open('zhao',"w"))
