从文件中读取字典并打印键

Question

基本上我试图在 python 中编写一个代码，从文件中获取字典。它应该打印显示的键。

{
    "Name": "namename",
    "Surname": "klsajdak",
    "Mhtrwo": "lsdkaslkd",
    "Phone": ["545454545454", "4554545454545"],
    "Age": 84,
    "kids": {
        "Name": "Zero",
        "Age": 0
    }
}

my_dict = open("9listes.txt", "r")

for key,value in my_dict.items():
    print("Key : {}".format(key))

Answer 1

您可以通过使用 json.load() 实现此目的：

import json

with open('9listes.txt') as f:
    my_dict = json.load(f)   # `my_dict ` is the `dict` you need

    # To print "key" & "value", uncomment below lines:
    # for key, value in my_dict.items():
    #     print("Key: {}, Value: {}".format(key, value))
