"python 查找 JSON 文件对象是否包含特定值"

Question

我有一个找到固定值的代码，但是我需要一个代码来检查一个 JSON 文件键是否包含特定值，我应该如何修改它，我是新手，我正在学习它

我的代码

import json

with open ('G:\\1.json', 'w', encoding='utf-8') as out:
    with open('G:\\1.json', encoding='utf-8') as j:
        for line in j:
            if (d := json.loads(line))['_source']['sex'] == 'female':
                print(json.dumps(d), file=out)

JSON文件

{"person":{"name":"Silva","sex":"female","age":21}}
{"person":{"name":"LANA","sex":"male","age":28}}
{"person":{"name":"Oliveira","sex":"female","age":35}}
{"person":{"name":"KENN","sex":"male","age":32}}

我要输出，“age”包含“2”

{"person":{"name":"Silva","sex":"female","age":21}}
{"person":{"name":"LANA","sex":"male","age":28}}
{"person":{"name":"KENN","sex":"male","age":32}}

Answer 1

如果要检查数字是否包含数字，请将其转换为字符串。

d = json.loads(line)
age_string = str(d['_source']['age'])
if "2" in age_string:
    print(json.dumps(d), file=out)
