pickle 都写文件

import pickle
mylist=[[1,2,3,4,5,6,7],["abc","xyz","hello"],[1,2,3,4,5,6,7,"我"]]
file=open(r"G:\我的python\尹成\python基础\day11\文件读写\list.bin","wb")
pickle.dump(mylist,file)  # 保存list到文件
file.close()

mylist = []
file = open(r"G:\我的python\尹成\python基础\day11\文件读写\list.bin","rb")
mylist = pickle.load(file)  # 读取文件到list

print(mylist)
file.close()
