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 parser topsecret['ForwardX11'] = 'no' # same here config['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']) # hg print(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 = 45 compression = yes compressionlevel = 9 forwardx11 = yes [bitbucket.org] user = hg [topsecret.server.com] host port = 50022 forwardx11 = no
