Python计算已经过去多少个周末的方法

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：
代码如下:
