如何实现Python中ini配置文件读写操作

这篇文章将为大家详细讲解有关如何实现Python中ini配置文件读写操作，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

导入模块

import configparser # py3

写入

config = configparser.ConfigParser()config["DEFAULT"] = {    'ServerAliveInterval': '45',    'Compression': 'yes',    'CompressionLevel': '9'    }config['bitbucket.org'] = {}config['bitbucket.org']['User'] = 'hg'config['topsecret.server.com'] = {}topsecret = config['topsecret.server.com']topsecret['Host Port'] = '50022'  # mutates the parsertopsecret['ForwardX11'] = 'no'  # same hereconfig['DEFAULT']['ForwardX11'] = 'yes'# 写入文件with open('example.ini', 'w') as configfile:    config.write(configfile)

读取

config = configparser.ConfigParser()config.read("example.ini")print(config.defaults())# OrderedDict([('compression', 'yes')])print(config.sections())# ['bitbucket.org', 'topsecret.server.com']print(config['bitbucket.org']['User'])# hgprint(config.options("topsecret.server.com"))# ['port', 'compression']print(config.items("topsecret.server.com"))# [('compression', 'yes'), ('port', '50022')]print(config.get("topsecret.server.com", "port"))# 50022

修改

print(config.has_section("Name"))# 删除config.remove_section("Name")# 添加config.add_section("Name")config["Name"]["name"] = "Tom"config["Name"]["asname"] = "Jimi"# 设置config.remove_option("Name", "asname")config.set("Name", "name", "Jack")# 保存config.write(open("example.ini", "w"))

附：ini文件

[DEFAULT]serveraliveinterval = 45compression = yescompressionlevel = 9forwardx11 = yes[bitbucket.org]user = hg[topsecret.server.com]host port = 50022forwardx11 = no

help(configparser)
