import json #json转换为字符串的特别是字符串两边是双引号，无论愿数据字符串是单引号还是双引号都会转换为 #双引号。包括字典里的key还是value都是一样变为双引号，只要反序列化的数据里的数据是双引号都可以用json。loads #获取不必非的用dumps转换过的 # cit={"A":1,"B":2,} # cit=json.dumps(cit) # with open("file","w") as f: #利用JSON.dumps序列化对象 #     f.write(cit) # with open("file") as f: #    data= json.loads(f.read()) #利用json.loads反序列化对象 #    print(data,type(data)) # with open("file1","w") as f: #     json.dump(cit,f) #json.dump只用于文件存取 代替了json.dumps(字典)+f.write(字典) # with open("file1") as f: #     data=json.load(f) #等同于data= json.loads(f.read()) #     print(data,type(data))

import pickle #类似于json，转换的为字节 # dic={"aa":1,"bb":2} # data=pickle.dumps(dic) # with open("file2","wb") as f: #     f.write(data) # with open("file2","rb") as f: #方法和json基本上类似 #     data=pickle.loads(f.read()) #     print(data,type(data))
import shelve #将一个字典放入文本 f={}
