Try this in your interactive interpreter:

>>> 9/5

What's odd about the result? "/" does integer division. It's weird and
unexpected to lots of people, but it's the way it is - it will be fixed in
due time. However, due to some time machine Guido is said to possess, you
can already use the future behavior by doing this:

from __future__ import division

Then try 9/5 again. Integer division is "//" now, while "/" behaves as
floating-point division.

Alternatively, you could use a floating-point number instead of integers.
Try this in a clean interpreter session (without the from __future__
thing):

>>> 9.0/5
>>> 9/5.0
>>> 9.0/5.0
