Google "python true division" -> I'm feeling lucky:
http://www.python.org/doc/2.2.3/whatsnew/node7.html
From the web page:
"""
* By including a from __future__ import division in a module(*), the /
operator will be changed to return the result of true division, so 1/2
is 0.5. Without the __future__ statement, / still means classic
division. The default meaning of / will not change until Python 3.0.
"""
*As the first non-docstring/non-comment line.
Note that that's for a module -- the interactive interpreter won't
respond the same way to the "from __future__ import" statement.
