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 = pmod(days_between,7)
if leftover:
start_day = (d2-timedelta(leftover)).isoweekday()
end_day = start_day+leftover
if start_day6:
weekends +=.5
if start_day7:
weekends +=.5
return weekends
使用方法：
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。
