我正在尝试返回除用户 ID 之外的所有用户的 JSON 列表

Answer 1

假设您拥有 JSON 的文件称为file.json ：

import json
with open('file.json') as f:
    d = json.loads(f)
    for key, value in d.items():
        del value['id']
        d[key] = value

或者，您可以使用以下内容：

import json
with open('file.json') as f:
    d = json.loads(f)
    for key, value in d.items():
        value.pop('id', None) // this will not crash if the element has no key 'id'

Answer 2

import json


with open('file.json') as fin:
    your_structure = json.load(fin)

for value in your_structure.values():
    value.pop('id', None)
