You don't say which python-version you have. Depending on that, the answer
is different.

In python2.5 and before, dividing two integers will always return an
integer.

So for your problem, you need to do

3.0 / 2.0 

At least one of the involved numbers must be a float.

However, from python2.5 the division operator behavior changed if desired -
if you do

>>> from __future__ import division
>>> 3 / 2
1.5
>>> 3 // 2
1


you get what you expect. The old division operator is still available, as //

In python2.6 and 3.x, the new behavior is standard.
