import datetime today = datetime.date.today()
yesterday = today - datetime.timedelta(days=1)
tomorrow = today - datetime.timedelta(days=1)
print yesterday,today,tomorrrow
书上写的逻辑我没写错,但是程序给我报错!书上说的是能出现
#输出：2004-11-7 2004-11-8 2004-11-9

Python 2.7 (r27:82525, Jul 4 2010, 09:01:59) [MSC v.1500 32 bit (Intel)] on win32

>>> import datetime
>>> today = datetime.date.today()
>>> oneday = datetime.timedelta(days=1)
>>> yesterday = today - oneday
>>> tommorrow = today + oneday
>>> print yesterday, today, tommorrow
