Python3中的Json与Pickle

用于将数据存取到文件中：

1：Json的存数据到文件：

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

2.Json的取数据

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

3.Pickle的存数据

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的取数据：

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

*若想实现Pickle的取数据（包含函数的复杂元素）必须要在取的时候声明函数。。。
