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。
