Python 通过pickle标准库加载和保存数据对象

import pickle

with open('mydata.pickle','wb') as mysavedata:
pickle.dump([1,2,'three'], mysavedata)
with open('mydata.pickle','rb') as myrestoredata:
a_list=pickle.load(myrestoredata)
print(a_list)

import pickle
import nester

new_man=[ ]
try:
with open('mydata.pickle','rb') as man_file:
new_man=pickle.load(man_file)
except IOError as err:
print('file error' + str(err))
except pickle.PickleError as perr:
print('pickling error' + str(perr))

nester.print_lol(new_man)
