本例是：本周三前一个礼拜的日期范围，包括今天
import datetime current_date = datetime.date.today() # days=2 代表礼拜三 # # current_date - datetime.timedelta(days=current_date.weekday()) 获取礼拜一日期 day = current_date - datetime.timedelta(days=current_date.weekday()) + datetime.timedelta(days=2) last_week_start = (day - datetime.timedelta(days=6)).strftime('%Y-%m-%d') last_week_end = (day - datetime.timedelta(days=0)).strftime('%Y-%m-%d') print(last_week_start, last_week_end)
