from datetime.datetime import today not working. python2.6.4 on windows

[Joshua Kordani]

Greetings all!

So I'm reading through the manual and I get to the point where it talks 
about packages and how to import them.  namely section 6.4 in the 
tutorial.  I wont repeat the section here, but I want to understand 
whats going on in the following (as typed on my computer).

Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit 
(Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> import datetime
 >>> dir(datetime)
['MAXYEAR', 'MINYEAR', '__doc__', '__name__', '__package__', 'date', 
'datetime',
  'datetime_CAPI', 'time', 'timedelta', 'tzinfo']
 >>> dir(datetime.datetime)
['__add__', '__class__', '__delattr__', '__doc__', '__eq__', 
'__format__', '__ge
__', '__getattribute__', '__gt__', '__hash__', '__init__', '__le__', 
'__lt__', '
__ne__', '__new__', '__radd__', '__reduce__', '__reduce_ex__', 
'__repr__', '__rs
ub__', '__setattr__', '__sizeof__', '__str__', '__sub__', 
'__subclasshook__', 'a
stimezone', 'combine', 'ctime', 'date', 'day', 'dst', 'fromordinal', 
'fromtimest
amp', 'hour', 'isocalendar', 'isoformat', 'isoweekday', 'max', 
'microsecond', 'm
in', 'minute', 'month', 'now', 'replace', 'resolution', 'second', 
'strftime', 's
trptime', 'time', 'timetuple', 'timetz', 'today', 'toordinal', 'tzinfo', 
'tzname
', 'utcfromtimestamp', 'utcnow', 'utcoffset', 'utctimetuple', 'weekday', 
'year']

 >>> from datetime.datetime import today
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: No module named datetime
 >>>

so dir on datetime shows symbols date, time, datetime,etc
dir on datetime shows today, now, etc

lets say for arguments sake that I want to just import the today 
function, according to the documentation, the line should be:
from datetime.datetime import today.

as you can see, that didn't work.  why not?
