本文实例讲述了Python计算已经过去多少个周末的方法。分享给大家供大家参考。具体如下：

def weekends_between(d1,d2):
  days_between = (d2-d1).days
  weekends, leftover = divmod(days_between,7)
  if leftover:
    start_day = (d2-timedelta(leftover)).isoweekday()
    end_day = start_day+leftover
    if start_day<=6 and end_day>6:
      weekends +=.5
    if start_day<=7 and end_day>7:
      weekends +=.5
  return weekends

使用方法：
复制代码 代码如下:weekends_between(date(2004,10,1),date(2004,10,10))

希望本文所述对大家的Python程序设计有所帮助。
