## Python的configparser读写配置文件 ##

假设配置文件为config.ini，里面原有的配置项内容为：

>     [kafak.server]
>     host = 99.99.99.99
>     port = 80
>     
>     [zookeeper.server]
>     host = 100.100.100.100
>     port = 2181
>     
>     [local]
>     client.port = 0
>     name = null

python读写更改config.ini里面的配置项：

import configparser as cfp
    
    if __name__ == '__main__':
        my_cfg = "./config.ini"
        config = cfp.ConfigParser()
        config.read(my_cfg)
    
        # 读取配置
    
        secs = config.sections()
        print(secs)
    
        print(config.options('kafak.server'))
        items = config.items('kafak.server')
        print(items)
        print(config.get('kafak.server', 'host'))
        print(config.get('kafak.server', 'port'))
    
        print(config.options('zookeeper.server'))
        items = config.items('zookeeper.server')
        print(items)
        print(config.get('zookeeper.server', 'host'))
        print(config.get('zookeeper.server', 'port'))
    
        # 写配置,更新配置
        config.set('local', 'client.port', '12345')
        config.set('local', 'name', 'zhangphil')
        f = open(my_cfg, 'w')
        config.write(f)
        f.close()

输出：

['kafak.server', 'zookeeper.server', 'local']
    ['host', 'port']
    [('host', '99.99.99.99'), ('port', '80')]
    99.99.99.99
    80
    ['host', 'port']
    [('host', '100.100.100.100'), ('port', '2181')]
    100.100.100.100
    2181

修改后的config.ini配置内容：

>     [kafak.server]
>     host = 99.99.99.99
>     port = 80
>     
>     [zookeeper.server]
>     host = 100.100.100.100
>     port = 2181
>     
>     [local]
>     client.port = 12345
>     name = zhangphil
