[Tutor] "from future import division"?

I'm running Python 2.2.2 (under Windows).  I want / to perform true 
division, not integer division.  That is, I want 1/2 to return 0.5, not 

"Python in a Nutshell" says this will be the default in 2.3, and until 
then, I can either include the line:

 from future import division

or invoke python as

 python -Qnew foo.py

the -Qnew option works, but the import does not:

  ImportError: No module named future

Any ideas?  Is my syntax wrong, or is there a "future" module that's
supposed to come with Python that's missing for me, but that I can
install?  Or is there some other change to the source code I can make to
cause Python to do true division?

I'd like to just use true division, rather than adding decimal points in
every operation to force true division, which looks messy (I'm doing a lot
of reciprocals), and without overriding the command line.
