Python的json and pickle序列化

Posted 2020-10-02

json序列化和json反序列化

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
__author__ = ‘人生入戏‘
import json

a = {
    "name":"test",
    "age":"20",
}
#json序列化
with open("json_test","w",encoding="utf-8") as f:
    f.write(json.dumps(a)) # 等同于这个 json.dump(a,f)

#json反序列化
with open("json_test","r",encoding="utf-8") as f:
    print(json.loads(f.read())) #等同于这个  print(json.load(f))

pickle序列化和反序列化

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
__author__ = ‘人生入戏‘
import pickle

def hello():
    print("Hello!")
    return 0
a = {
    "name":"test",
    "age":"20",
    "func":hello
}
with open("json_test","wb") as f:
    f.write(pickle.dumps(a))  #等同于这个 pickle.dump(a,f)

with open("json_test","rb") as f:
    print(pickle.loads(f.read())["func"]()) #等同于这个 print(pickle.load(f)["func"]())
