如何选择一年中的所有星期日(或任何一天)?

How can I select all of the Sundays (or any day for that matter) in a year?

[ '01/03/2010','01/10/2010','01/17/2010','01/24/2010', ...]

这些日期代表 2010 年的星期日.我想这也适用于一周中的任何一天.

These dates represent the Sundays for 2010. This could also apply to any day of the week I suppose.

推荐答案

您可以使用 date" rel="noreferrer">datetime 模块查找一年中的第一个星期日，然后不断增加 7 天，生成新的星期日:

You can use date from the datetime module to find the first Sunday in a year and then keep adding seven days, generating new Sundays:

from datetime import date, timedelta

def allsundays(year):
   d = date(year, 1, 1)                    # January 1st
   d += timedelta(days = 6 - d.weekday())  # First Sunday
   while d.year == year:
      yield d
      d += timedelta(days = 7)

for d in allsundays(2010):
   print(d)
