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 cfpif __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
