如何在python配置文件中存储字典和列表？ [英] How to store dictionary and list in python config file?

问题描述

我正在使用config.ini文件存储所有配置。

I'm using config.ini file to store all my configurations.

我需要在配置文件中存储字典和列表，并在我的文件中解析它使用configparser的main.py文件。谁能告诉我我该怎么做？

I need to store a dictionary and a list in the config file and parse it in my main.py file using configparser. Can anyone please tell me how do I go about doing that?

config.ini：

config.ini:

[DEFAULT] 
ADMIN = xyz 
SOMEDICT = {'v1': 'k1', 'v2': 'k2'}
SOMELIST = [v1, v2]

main.py：

config = configparser.ConfigParser() 
config.read('config.ini') 
secret_key = config['DEFAULT']['ADMIN']

如果没有办法，以json格式配置是否是一个好选择？

If there is no way to do this, is config in json format a good option?

推荐答案

ConfigParser只会将这些元素作为字符串提供给您，然后您需要对其进行解析。

ConfigParser will only ever give you those elements as strings, which you would then need to parse.

作为替代，YAML是易于阅读的配置文件的不错选择。您的文件可能看起来像这样：

As an alternative, YAML is a good choice for configuration files, since it is easily human readable. Your file could look like this:

DEFAULT:
    ADMIN: xyz
    SOMEDICT:
        v1: k1
        v2: k2
    SOMELIST:
        - v1
        - v2

，Python代码将是：

and the Python code would be:

import yaml
with open('config.yml') as c:
    config = yaml.load(c)
config['DEFAULT']['SOMEDICT']
