第一步：生成三个字典并写入到内存中

import json

name_dict = {"张三": 25, "李四": 30, "王五": 28}
age_dict = {"张三": 25, "李四": 30, "王五": 28}
gender_dict = {"张三": "男", "李四": "女", "王五": "男"}

with open("data.json", "w", encoding="utf-8") as f:
    json.dump({"name": name_dict, "age": age_dict, "gender": gender_dict}, f, ensure_ascii=False)

第二步：设计一个修改模块，修改他们的姓名、年龄、性别并替换到内存中

def update_info(name, age, gender):
    with open("data.json", "r", encoding="utf-8") as f:
        data = json.load(f)

    data["name"][name] = age
    data["age"][name] = age
    data["gender"][name] = gender

    with open("data.json", "w", encoding="utf-8") as f:
        json.dump(data, f, ensure_ascii=False)

# 示例：修改张三的信息
update_info("张三", 26, "男")
