上周五如何获得？

与链接的问题一样，您需要使用

datetime.date

对象而不是

datetime.datetime

。要获得

datetime.datetime

最终结果，可以使用

datetime.datetime.combine()

：

import datetimecurrent_time = datetime.datetime.now()# get friday, one week ago, at 16 o'clocklast_friday = (current_time.date()    - datetime.timedelta(days=current_time.weekday())    + datetime.timedelta(days=4, weeks=-1))last_friday_at_16 = datetime.datetime.combine(last_friday, datetime.time(16))# if today is also friday, and after 16 o'clock, change to the current dateone_week = datetime.timedelta(weeks=1)if current_time - last_friday_at_16 >= one_week:    last_friday_at_16 += one_week
