Python里的数据存储模块：pickle使用方法

import pickle

data_list = [1,2,3]
data_dic = {
    'a':'111',
    'b':'222',
    'c':'333'
    }

#dump()将数据序列化到文件中
fw = open('test.txt','wb')
pickle.dump(data_list, fw)
pickle.dump(data_dic, fw)
fw.close()

#load()将数据从文件中序列化读出
fr = open('test.txt','rb')
data_list_load = pickle.load(fr)
print(data_list_load)
data_dic_load = pickle.load(fr)
print(data_dic_load)
fr.close()
