python 读写ini文件 设置保存与读取

import configparser,sys

cf = configparser.ConfigParser()
#写INI
def xini():
    executor_url = "100"
    session_id = "6666"
    cf.add_section("ssh")
    cf.set("ssh","executor_url",executor_url)
    cf.set("ssh","session_id",session_id)
    cf.write(open("my.ini","w"))
    sys.exit(0)
#读ini文件
ac=cf.read("my.ini")
executor_url = cf.get("ssh","executor_url")
session_id = cf.get("ssh","session_id")
print(executor_url,session_id)
##>>> cf.items("ssh")
##[('executor_url', '100'), ('session_id', '6666')]
##>>> cf.getint("db","port")读取数值
