Json与Pickle ：功能主要用于文件数据序列化操作
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"]()
*pickle 读写都是采用二进制，所以要使用‘rb‘ & ‘wb‘
