config["DEFAULT"] = {‘ServerAliveInterval‘: ‘45‘,
                     ‘Compression‘: ‘yes‘,
                     ‘CompressionLevel‘: ‘9‘}  #使用字典的方式给config赋值

topsecret = config[‘topsecret.server.com‘]

topsecret[‘ForwardX11‘] = ‘no‘  # same here

with open(‘example.ini‘, ‘w‘) as f:
    config.write(f)  #将删除内容写入文件

#生成文件的内容如下
#[DEFAULT]
#serveraliveinterval = 45
#compression = yes
#compressionlevel = 9

#[bitbucket.org]
#user = hg

#[topsecret.server.com]
#host port = 50022
#forwardx11 = no

config.read(‘example.ini‘)  #读取文件
print(config.sections())  #config.sections()返回一个列表[‘bitbucket.org‘, ‘topsecret.server.com‘]，包含除了DEFAULT之外的块名，需要事先读取文件
print(config[‘bitbucket.org‘][‘user‘])  #使用字典的方式取值
print(config[‘DEFAULT‘][‘compression‘])

for i in config[‘bitbucket.org‘]:
    print(i)
#输出结果如下
# user
# serveraliveinterval
# compression
# compressionlevel

print(config.options(‘bitbucket.org‘))
print(config.items(‘bitbucket.org‘))
#输出内容如下
# [‘user‘, ‘serveraliveinterval‘, ‘compression‘, ‘compressionlevel‘]
# [(‘serveraliveinterval‘, ‘45‘), (‘compression‘, ‘yes‘), (‘compressionlevel‘, ‘9‘), (‘user‘, ‘hg‘)]
