您可以执行以下操作
In [6]: import datetime
# Today
In [7]: datetime.datetime.now()
Out[7]: datetime.datetime(2013, 1, 15, 15, 31, 10, 760000)
# Tomorrow's date
In [8]: print datetime.datetime.now() + datetime.timedelta(days=1)
2013-01-16 15:31:15.336000
# Day after tomorrow's day
In [9]: print datetime.datetime.now() + datetime.timedelta(days=2)
2013-01-17 15:31:52.601000
# Yesterday's date
In [10]: print datetime.datetime.now() - datetime.timedelta(days=1)
2013-01-14 15:32:00.081000
也适用于datetime.datetime.today()
In [15]: datetime.datetime.today()
Out[15]: datetime.datetime(2013, 1, 15, 15, 34, 37, 55000)
In [16]: datetime.datetime.today() + datetime.timedelta(days=1)
Out[16]: datetime.datetime(2013, 1, 16, 15, 34, 47, 560000)
