• json只能用於簡單的數據類型，例如：字典啊，列表啊，字符串之類的，無法處理復雜的，例如帶有函數的
• json適用於所有的開發語言
• dumps與loads只對應使用一次，若dumps多次，則loads出錯

• import json json.dumps() and json.loads()

import json

info = {
    "name":"alex",
    "age": 23
}
f = open("test.txt","w",encoding="utf-8")
f.write(json.dumps(info))
f.close()

import json

f = open("test.txt","r",encoding="utf-8")
data = json.loads(f.read())
print(data)

• import json json.dump() and json.load()

import json

info = {
    "name":"alex",
    "age": 23
}
f = open("test.txt","w",encoding="utf-8")
json.dump(info,f) #相當於f.write(json.dumps(info))
 

f.close()

import json

f = open("test.txt","r",encoding="utf-8")
data = json.load(f)#相當於data = json.loads(f.read())
print(data)
f.close()

• import pickle 處理復雜類型：只適用於python

import pickle

def func(name):
    print("name",name)
info = {
    "name":"alex",
    "age": 23,
    
 
"function":func

}
f = open("test.txt","wb")
f.write(pickle.dumps(info))

f.close()

import pickle
def func(name):
    print("name",name)
    print("這裏只保存了對應函數的名稱，有相應的名稱則能使用，裏面的內容可以不同")

f = open("test.txt","rb")
data = pickle.loads(f.read())
print(data)
f.close()

json and pickie 序列化
