模块找到第一个星期天一年,然后继续添加七天,产生新的星期日:
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
