python 模块configparser 配置文件模块
import configparser
config = configparser.ConfigParser()
config["DEFAULT"] = {'ServerAliveInterval': '45',
'Compression': 'yes',
'CompressionLevel': '9'}
config['bitbucket.org'] = {'User': 'hg'}
config['topsecret.server.com'] = {'Host Port'：'50022'，
'ForwardX11'，'no'}with open('example.ini', 'w') as configfile: #把键值对写入 配置文件example.ini
config.write(configfile)
结果：
[DEFAULT]
ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes [bitbucket.org]
User = hg [topsecret.server.com]
Port = 50022
ForwardX11 = no
config.read('example.ini') # 关联文件才能操作里面键值
print(config.sections()) #['bitbucket.org', 'topsecret.server.com'] 查看段
print('bytebong.com' in config)# False 判断
print(config['bitbucket.org']['User']) # hg 查看值
print(config['DEFAULT']['Compression']) #yes 查看值
print(config['topsecret.server.com']['ForwardX11']) #no 查看值
for key in config['bitbucket.org']: #循环打印[bitbucker.org]的键
print(key)
###打印段[bitbucker.org]的所有键
print(config.options('bitbucket.org'))#['user', 'serveraliveinterval', 'compression', 'compressionlevel', 'forwardx11']
###循环打印段[bitbucker.org]的所有键值
print(config.items('bitbucket.org')) #[('serveraliveinterval', '45'), ('compression', 'yes'), ('compressionlevel', '9'), ('forwardx11', 'yes'), ('user', 'hg')]
###打印段[bitbucket.org] 键compression 的值
print(config.get('bitbucket.org','compression'))#yes
config.add_section('yuan') #增加一个段 [yuan]
config.remove_section('topsecret.server.com') # 删除一个段[topsecret.server.com]
config.remove_option('bitbucket.org','user') # 删除这个[bitbucket.org]段里面的键和值User = hg
config.set('bitbucket.org','k1','11111') # 添加[bitbucket.org]段里面 键值 k1 = 11111
config.write(open('i.cfg', "w") # 写入的话 必须先执行这条命令
