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)
