Note: always cut and paste the *precise* error message
(and preferably the *precise* command you entered)
when you are reporting a problem.  This avoids confusion.

In this case, I'm assuming what you saw looked more like:

[phansen]$ test.py
bash: test.py: command not found

If this is the case, you should probably try ./test.py 
instead.  The shell does not execute files which are not
in one of the directories in the PATH unless you refer
to them explicitly (relative or absolute path).  If you
move the file to somewhere in the PATH it should work.

The other problem could be that your python is not 
really in /usr/bin (type "which python" to be sure)
but then your error message would say:

bash: ./test.py: No such file or directory

(This all on Red Hat release 7.1.)
