如何在python中计算一周的第一个日期和一周的最后一个日期 [英] Howto calculate first date of week and last date for week in python

问题描述

我需要在python中计算一周的日期

I need Calculate dates for week in python

我需要这个

year = 2012
week = 23
(a,b) = func (year,week)
print a
print b

>>>2012-04-06
>>>2012-06-10

你能帮我吗?

推荐答案

日期对象包含 weekday()方法.

这在星期日的6号星期一返回0.

This returns 0 for monday 6 for sunday.

(From googling) here is one solution: http://www.protocolostomy.com/2010/07/06/python-date-manipulation/ )

我认为这可以使冗长一些，所以这是我的目的:

I think this can be made a little less verbose so here's my stab at it:

def week_magic(day):
    day_of_week = day.weekday()

    to_beginning_of_week = datetime.timedelta(days=day_of_week)
    beginning_of_week = day - to_beginning_of_week

    to_end_of_week = datetime.timedelta(days=6 - day_of_week)
    end_of_week = day + to_end_of_week

    return (beginning_of_week, end_of_week)
