在for循环里用time，datetime等的小坑

可能是bug的原因，在for循环里用buytime = time.strptime(buytime, "%M:%S")以及 y = date( int(buydate[0:4]), int(buydate[4:6]), int(buydate[6:8])).weekday() + 1会报 ‘list’is Not 巴拉巴拉的错误。经楼主测试后发现，进行如下的别名设置——import datetime as dtimport time as ti而后：y = dt.date(int(buydate[0:4]), int(buydate[4:6]), int(buydate[6:8])).weekday() + 1buytime = ti.strptime(buytime, "%M:%S")即可解决这个问题！
