import configparser #引入模块

config = configparser.ConfigParser()    #类中一个方法 #实例化一个对象

config["DEFAULT"] = {‘ServerAliveInterval‘: ‘45‘,
                      ‘Compression‘: ‘yes‘,
                     ‘CompressionLevel‘: ‘9‘,
                     ‘ForwardX11‘:‘yes‘
                     }	#类似于操作字典的形式

config[‘bitbucket.org‘] = {‘User‘:‘Atlan‘} #类似于操作字典的形式

config[‘topsecret.server.com‘] = {‘Host Port‘:‘50022‘,‘ForwardX11‘:‘no‘}

   config.write(configfile)	#将对象写入文件

#config后面跟的是一个section的名字，section的段的内容的创建类似于创建字典。类似与字典当然还有别的操作方式啦！
config[‘bitbucket.org‘] = {‘User‘:‘Atlan‘}  #类似与最经典的字典操作方式

#---------------------------查找文件内容,基于字典的形式

print(config.sections())        #  []

print(‘bytebong.com‘ in config) # False
print(‘bitbucket.org‘ in config) # True


print(config[‘bitbucket.org‘]["user"])  # Atlan

print(config[‘DEFAULT‘][‘Compression‘]) #yes

print(config[‘topsecret.server.com‘][‘ForwardX11‘])  #no


print(config[‘bitbucket.org‘])          #<Section: bitbucket.org>

for key in config[‘bitbucket.org‘]:     # 注意,有default会默认default的键
    print(key)

print(config.options(‘bitbucket.org‘))  # 同for循环,找到‘bitbucket.org‘下所有键

print(config.items(‘bitbucket.org‘))    #找到‘bitbucket.org‘下所有键值对

print(config.get(‘bitbucket.org‘,‘compression‘)) # yes       get方法Section下的key对应的value

import configparser

config = configparser.ConfigParser()

config.read(‘example.ini‘)  #读文件

config.add_section(‘yuan‘)  #添加section

config.remove_section(‘bitbucket.org‘) #删除section
config.remove_option(‘topsecret.server.com‘,"forwardx11") #删除一个配置想

config.set(‘topsecret.server.com‘,‘k1‘,‘11111‘)
config.set(‘yuan‘,‘k2‘,‘22222‘)

     config.write(f)
