Python_pickle

pickle是一个可以将任意一个对象存储在硬盘文件中的工具。

更新:Python3中用法变了:  https://www.cnblogs.com/fmgao-technology/p/9078918.html

ref:https://docs.python.org/2/library/pickle.html

常用的用法就两个。。。dump(写入文件)和load(从文件中读)

 

demo:

 1 __author__ = 'IBM'
 2 import pickle
 3 
 4 fp="D:/pycharmprojects/pickle_demo/r.pkl"
 5 
 6 data="233333_woshihanbazi"
 7 with open(fp,"wb") as f:
 8     pickle.dump(data,f)
 9 
10 with open(fp,"rb") as f:
11     dat=pickle.load(f)
12 print(dat)

Output:

233333_woshihanbazi
