生成example.ini文件

import configparser
config = configparser.ConfigParser()
#---------------------------查找文件内容,基于字典的形式
print(config.sections())        #  []
config.read('example.ini')
print(config.sections())        #   ['bitbucket.org', 'topsecret.server.com']

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

print(config['bitbucket.org']["user"])  # hg
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 元组形式
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')   # 增加section
config.remove_section('bitbucket.org')   # 删除一个section
config.remove_option('topsecret.server.com',"forwardx11")  # 删除一个配置项
config.set('topsecret.server.com','k1','11111')
config.set('yuan','k2','22222')
f = open('new2.ini', "w")
config.write(f) # 写进文件
f.close()
