在Python中迭代JSON文件

您面临的问题是,您将数据作为单个json。

你需要把它做成一个数组。像这样的。

[{  // notice additional [
    "firstName": "Jane",
    "lastName": "Doe",
    "hobbies": ["running", "sky diving", "singing"],
    "age": 35,
    "children": [
        {
            "firstName": "Alice",
            "age": 6
        },
        {
            "firstName": "Bob",
            "age": 8
        }
    ]
},
{
    "firstName": "Mike",
    "lastName": "Smith",
    "hobbies": ["bowling", "photography", "biking"],
    "age":40,
    "children": [
        {
            "firstName": "Steve",
            "age": 10
        },
        {
            "firstName": "Sara",
            "age": 18
        }
    ]
}]  // notice additional ]

import json

with open('abc.json') as f:
    data = json.load(f)

for element in data:
    for key, value in element.items():
        print(key, value)

把你的档案藏起来会更危险 JSON ,然后打开它 [ 和 ]

import json

f = open("test_json.txt", "r")
contents = f.readlines()
f.close()


contents.insert(0, "[")

f = open("test_json.txt", "w")
contents = "".join(contents)
f.write(contents)
f.write("]")
f.close()


with open("test_json.txt", "r") as fd:
    d = json.load(fd)
    for i in d:
        print(i)
