pickle模块练习

示例1：讲一个列表以二进制形式保存

#!/usr/bin/python
import pickle
my_list = [12,3.14,'chenzhitao',[1,2,3]]
pickle_file = open('my_list.pkl','wb')
pickle.dump(my_list,pickle_file)
pickle_file.close()

示例2：将二进制文件读出来

#!/usr/bin/python
import pickle
pickle_file = open('my_list.pkl','rb')
my_list = pickle.load(pickle_file)
print(my_list)
