序列化模組注意點 json&pickle&shelve

標籤：序列化   結果   注意   dump   res   name   enc   utf-8   檔案   

 

dic = {‘k1‘:‘v1‘}print(type(dic),dic)import jsonstr_d = json.dumps(dic)print(type(str_d),str_d)dic_d = json.loads(str_d)print(type(dic_d),dic_d)

結果:

<class ‘dict‘> {‘k1‘: ‘v1‘}<class ‘str‘> {"k1": "v1"}<class ‘dict‘> {‘k1‘: ‘v1‘}

 

-------

 

import jsondic = {‘k1‘:‘v1‘}f = open(‘fff‘,‘w‘,encoding=‘UTF-8‘)json.dump(dic,f)f.close()f = open(file = ‘fff‘,mode = ‘r‘,encoding=‘UTF-8‘)res = json.load(f)f.close()print(type(res),res)

 

結果:

<class ‘dict‘> {‘k1‘: ‘v1‘}

並且產生一個檔案,filename為fff,裡面儲存了一個dic

 

dumps&loads

序列化&還原序列化(對記憶體操作)

dump&load

(對檔案操作)
