如何查询json文件中的数据如果存在用python添加额外的字段

import json

with open('file.json', 'r') as f:
    data = json.load(f)

if 'key' in data:
    data['new_key'] = 'new_value'

with open('file.json', 'w') as f:
    json.dump(data, f)

import json

with open('file.json', 'r') as f:
    data = json.load(f)

if 'key' in data:
    data['new_key'] = 'new_value'

with open('file.json', 'w') as f:
    json.dump(data, f)
