Python 3.x--序列化及反序列化

1、JSON序列化

import json

#将字典写入文件,JSON序列化（dumps）a = {    ‘name‘:‘lili‘,    ‘age‘:22,    ‘salary‘:2000}

with open(‘file01.txt‘,‘w‘) as f:    f.write(json.dumps(a))

2、JSON反序列化

#将文件读出，并显示为字典，JSON反序列化（loads）

with open(‘file01.txt‘,‘r‘) as f1:    line = json.loads(f1.read())    print(line[‘age‘])

3、Pickle序列化

------dumps方法------

import pickle

def func1(name):    print(‘hello‘,name)

a = {    ‘name‘:‘lili‘,    ‘age‘:22,    ‘salary‘:2000,    ‘arge‘:func1}

with open(‘file01.txt‘,‘wb‘) as f:    f.write(pickle.dumps(a))

------dump方法------

import pickle

def func1(name):    print(‘hello..‘,name)

a = {    ‘name‘:‘lili‘,    ‘age‘:22,    ‘salary‘:2000,    ‘arge‘:func1}

with open(‘file01.txt‘,‘wb‘) as f:    pickle.dump(a,f)

4、Pickle反序列化

------loads方法------

with open(‘file01.txt‘,‘rb‘) as f1:    def func1(name):        print(‘hello‘, name)    line = pickle.loads(f1.read())    print(line[‘arge‘](‘lili‘))

运行结果：

------load方法------

with open(‘file01.txt‘,‘rb‘) as f1:    data = pickle.load(f1)    print(data)
