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
