Json與Pickle ：功能主要用於文件數據序列化操作

　　1：Json的存數據到文件：

import json
info = {
    "name":"hjc",
    "age":22
}
with open("a1.txt","w",encoding="utf-8") as f:
    f.write(json.dumps(info))

　　2.Json的取數據

import json
with open("a1.txt","r",encoding="utf-8") as f:
    data = json.loads(f.readline())
    print(data["age"])

　　3.Pickle的存數據

import pickle
 
def func():
    print("hello tomorrow!!!")
 
info = {
    "name" : "hjc",
    "age" : 24,
    "hobby" : func
}
with open("a1.txt","wb") as f:
    f.write(pickle.dumps(info))

　　4.Pickle的取數據：

import pickle
 
def func():
    print("hello tomorrow!!!")
 
with open("a1.txt","rb") as f:
    data = pickle.loads(f.read())
data["hobby"]()

　　*pickle 讀寫都是采用二進制，所以要使用‘rb‘ & ‘wb‘
