# configparse
# import configparser
# config = configparser.ConfigParser()  #config就像一个文件句柄
# config["DEFAULT"] = {'ServerAliveInterval': '45',
# 'Compression': 'yes',
# 'CompressionLevel': '9',
# 'ForwardX11':'yes'
# }
# config['bitbucket.org'] = {'User':'hg'}
#

#
# with open('example.ini', 'w') as f:

# 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
#
# 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()
