方法一:
>>> import calendar >>> calendar.monthrange(2002,1) (1, 31) >>> calendar.monthrange(2008,2) (4, 29) >>> calendar.monthrange(2100,2) (0, 28) >>> calendar.monthrange(2016, 2)[1]
方法二:
import datetime for x in xrange(1, 13): dt_start = (datetime.datetime(2016, x, 1)).strftime("%Y%m%d") if 12 == x: dt_end = (datetime.datetime(2016, 12, 31)).strftime("%Y%m%d") else: dt_end = (datetime.datetime(2016, x+1, 1) - datetime.timedelta(days = 1)).strftime("%Y%m%d") print dt_start, dt_end
