python configparser

1、创建文件

import configparser

cf = configparser.ConfigParser()
cf.add_section('mysqld')
cf.set('mysqld','port','3306')
cf.set('mysqld','max_connection','1000')
cf.add_section('client')
cf.set('client','pid','/tmp/user.pid')
cf.set('client','basedir','/var/usr/lib/mysql')
with open('my.ini','w') as f:
    cf.write(f)

2、读取文件

cf = configparser.ConfigParser()
cf.read('my.ini')
print(cf['mysqld']['port'])
