configparser模块 (37min day18)

import configparser

config = configparser.ConfigParser()

config["DEFAULT"] = {'ServerAliveInterval': '45',
                     'Compression': 'yes',
                     'CompressionLevel': '9'}
#
# config['bitbucket.org'] = {}
#
# config['bitbucket.org']['User'] = 'hg'
config['bitbucket.org'] = {'User':'hg'} #与上面一致


config['topsecret.server.com'] = {}

topsecret = config['topsecret.server.com']
topsecret['Host Port'] = '50022'  # mutates the parser
topsecret['ForwardX11'] = 'no'  # same here

config['DEFAULT']['ForwardX11'] = 'yes'

with open('example.ini', 'w') as configfile: #创建，写
    config.write(configfile)

#读
config.read('example.ini')
print(config.sections()) #默认的不读出
print(config.defaults()) #有序字典
print('')
print(config['bitbucket.org']['User'])
print('')
for key in config['bitbucket.org']:
    print(key) #本来只能输出　user键，但是默认的键也输出
print('')
config.remove_section('topsecret.server.com')

print(config.has_section('topsecret.server.com')) #已被删，无法找到

config.set('bitbucket.org','user','alex')#修改值

config.write(open('i.cfg',"w"))#也可以写成同名文件example.ini，但那属于覆盖，不属于删除

执行结果：

['bitbucket.org', 'topsecret.server.com']
OrderedDict([('compressionlevel', '9'), ('serveraliveinterval', '45'), ('compression', 'yes'), ('forwardx11', 'yes')])
