configparser模块用于处理特定格式的文件，本质上是利用open来操作文件。

#!/usr/bin/env python# coding=utf-8import configparserconfig = configparser.ConfigParser()config.read('conf.conf', encoding='utf-8')ret = config.sections()  # 获取所有节点名ret = config.items('section1')  # 获取section1 的键值对ret = config.options('section1')  # 获取section1的所有键ret = config.get('section1', 'k3')  # 获取section1某一键的值# ret = config.getint('section1', 'k1')  # 获取section1键k1的值并转换为int类型, 类型有getfloat, getbooleanprint(ret)# 检测节点has_sec = config.has_section('section1')print(has_sec)# 添加节点# config.add_section('section4')# config.write(open('conf.conf', 'w'))# 删除节点config.remove_section('section2')config.write(open('conf.conf', 'w'))# 检测指定节点的键值对has_opt = config.has_option('section1', 'k1')print(has_opt)# 删除指定节点的键值对#config.remove_option('section1', 'k1')#config.write(open('conf.conf', 'w'))# 添加指定节点的键值对config.set('section1', 'k1', '111')config.write(open('conf.conf', 'w'))
