Python操作Json文件

#导入模块
import json

# 将json对象转成字典 -> 进行解码
with open("myjson.json", "r", encoding="utf-8") as f:

    # 获取文件中数据 -> 字典
    new_dict = json.load(f)
    print(new_dict["键"])#通过键拿到值

#导入模块
import json

# 定义一个字典
my_dict = {"name": "坡哥", "age": 30, "Id": "No.1"}

# 将字典转成json -> 进行编码
json_str = json.dumps(my_dict)
# 把json数据写入到文件中
with open("myjson.json", "w", encoding="utf-8") as f:
    f.write(json_str)
