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
