python 配置文件操作模块 configobj

1. 安装模块
   

   pip install configobj

   测试用配置文件内容：
   

   [DEFAULT]
   appid =
   appkey =

    

2. 读取配置文件
   

   from configobj import ConfigObj
   
   config = ConfigObj("config.ini", encoding='utf-8')

   appid = config['DEFAULT']['appid']
   
   appkey = config['DEFAULT']['appkey']　　

   最好做个判断，如果节点不存在，程序就会报错
   
   

       if 'DEFAULT' in config and 'appkey' in config['DEFAULT']:  # 判断节点是否存在
           if config['DEFAULT']['appkey'] != "":  # 判断值是否为空
               appkey = config['DEFAULT']['appkey']
           else:
               appkey = 'xxxxxx'
       else:
           appkey = 'xxxxxx'

    

3. 修改配置
   

   config = ConfigObj("config.ini", encoding='UTF-8')
   config['DEFAULT']['appid'] = "xxx"
   # 保存配置文件
   config.write()

    

4. 添加新项
   

   config['client'] = {}
   config['client']['type'] = "general"
   # 保存配置
   config.write()

    

5. 删除某项配置
   

   del config['client']
   del config['client']['type']
   config.write()

    

6. 保存配置到新文件
   

   config = ConfigObj("config.ini")
   
   config.filename = "config2.ini"
   config.write()

    

7. 创建默认配置文件
   

   config = ConfigObj()
   config.filename = "config.ini"
   
   config["DEFAULT"] = {"appid":"1111","appkey":"2222"}
   config.write()
