Pythno计算过去了多少个周末。

# Python代码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参考使用：weekends_between(date(2014,10,1),date(2014,10,10))
