json到仅显示列表的Python转换

Question

我想知道这里是否有专家的帮助。在python中，我想转换这个json。目前是：

{
    "comics": "marvel",
    "comicname": [
        "Spiderman",
        "Avengers",
        "Captain Marvel"
    ]
}

我希望它是这样的。只有comicname列表：

{
    "comicname": [
        "Spiderman",
        "Avengers",
        "Captain Marvel"
    ]
}

Answer 1

import json

my_dict = {
    "comics": "marvel",
    "comicname": [
        "Spiderman",
        "Avengers",
        "Captain Marvel"
    ]
}

# Remove unwanted key.
del my_dict["comics"]

# Turn dictionary into json string and print it.
print(json.dumps(my_dict))

如果有时间，您应该检查一下json模块

Answer 2

你可以在这里做两件事。根据你的要求，我建议的第一个

代码1 删除“漫画”：“惊奇漫画”

x = {
    "comics": "marvel",
    "comicname": [
        "Spiderman",
        "Avengers",
        "Captain Marvel"
    ]
}
del x["comics"]
print(x)

代码2 仅显示“comicname”：列表[]

x = {
    "comics": "marvel",
    "comicname": [
        "Spiderman",
        "Avengers",
        "Captain Marvel"
    ]
}
x = x["comicname"]
print(x)

Answer 3

两个快速选项：

1-创建一个新对象

original_object = {
    "comics": "marvel",
    "comicname": [
        "Spiderman",
        "Avengers",
        "Captain Marvel"
    ]
}

new_object = {
    'comicname': original_object['comicname']
    }

print(new_object)

2-从原始漫画中删除“漫画”：

original_object = {
    "comics": "marvel",
    "comicname": [
        "Spiderman",
        "Avengers",
        "Captain Marvel"
    ]
}

del original_object["comics"]
print(original_object)
