Python:2010年7月的最后一个星期一

Question

如何获得给定月份的最后一个星期一(或其他日期)？

Answer 1

看看dateutil:

from datetime import datetime
from dateutil import relativedelta
datetime(2010,7,1) + relativedelta.relativedelta(day=31, weekday=relativedelta.MO(-1))

回报

datetime.datetime(2010, 7, 26, 0, 0)

Answer 2

使用stdlib中的日历模块:

import calendar
cal = calendar.Calendar(0)
month = cal.monthdatescalendar(2010, 7)
lastweek = month[-1]
monday = lastweek[0]
print(monday)

2010-07-26
