json 模块 与 pickle 模块

 1 import json

 3 dic={'name':'alvin','age':23,'sex':'male'}
 4 print(type(dic))#<class 'dict'>

 6 j=json.dumps(dic)
 7 print(type(j))#<class 'str'>

10 f=open('序列化对象','w')
11 f.write(j)  #-------------------等价于json.dump(dic,f)
12 f.close()
13 #-----------------------------反序列化<br>
14 import json
15 f=open('序列化对象')
16 data=json.loads(f.read())#  等价于data=json.load(f)

 1 import pickle

 3 dic={'name':'alvin','age':23,'sex':'male'}

 5 print(type(dic))#<class 'dict'>

 7 j=pickle.dumps(dic)
 8 print(type(j))#<class 'bytes'>

11 f=open('序列化对象_pickle','wb')#注意是w是写入str,wb是写入bytes,j是'bytes'
12 f.write(j)  #-------------------等价于pickle.dump(dic,f)

14 f.close()
15 #-------------------------反序列化
16 import pickle
17 f=open('序列化对象_pickle','rb')

19 data=pickle.loads(f.read())#  等价于data=pickle.load(f)

22 print(data['age']
