使用Python的标准库pickle来处理数据达到保存和恢复的效果

1.小例子

import pickle        

with open('mydata.pickle', 'wb') as mysavedata:        #创建mydata.pickle文件，'wb'以二进制进行存储
    pickle.dump([1, 2, 'three'], mysavedata)        #使用pickle.dump保存数据

with open('mydata.pickle', 'rb') as myrestoredata:        
    a_list = pickle.load(myrestoredata)        #使用pickle.load恢复数据

print(a_list)
