如何将字典列表保存到文件中? [英] How can I save a list of dictionaries to a file?

问题描述

我有一个字典列表.有时，我想更改并保存这些词典之一，以便在重新启动脚本时利用新消息.现在，我通过修改脚本并重新运行来进行更改.我想将其从脚本中删除，并将字典列表放入某种配置文件中.

I have a list of dictionaries. Occasionally, I want to change and save one of these dictionaries so that the new message is utilized if the script is restarted. Right now, I make that change by modifying the script and rerunning it. I'd like to pull this out of the script and put the list of dictionaries into a configuration file of some kind.

我找到了有关如何将列表写入文件的答案，但这假定它是一个平面列表.如何使用词典列表呢?

I've found answers on how to write a list to a file, but this assumes that it is a flat list. How can I do it with a list of dictionaries?

我的列表如下:

logic_steps = [
    {
        'pattern': "asdfghjkl",
        'message': "This is not possible"
    },
    {
        'pattern': "anotherpatterntomatch",
        'message': "The parameter provided application is invalid"
    },
    {
        'pattern': "athirdpatterntomatch",
        'message': "Expected value for debugging"
    },
]

推荐答案

假定该对象仅包含JSON可以处理的对象(lists，tuples，strings，dicts，numbers，None，True和False)，则可以将其转储为 json.dump :

provided that the object only contains objects that JSON can handle (lists, tuples, strings, dicts, numbers, None, True and False), you can dump it as json.dump:

import json
with open('outputfile', 'w') as fout:
    json.dump(your_list_of_dict, fout)
