我应该如何遍历这个JSON数据？

const jsonData = '{"name": "Alice", "age": 25, "city": "New York"}';
const obj = JSON.parse(jsonData);

for (let key in obj) {
  if (obj.hasOwnProperty(key)) {
    console.log(key + ": " + obj[key]);
  }
}

import json

json_data = '{"name": "Alice", "age": 25, "city": "New York"}'
obj = json.loads(json_data)

for key, value in obj.items():
  print(key + ": " + str(value))
