Never trust the assumption:

 >>> import os
 >>> os.path.isfile( os.path.join(os.path.dirname( sys.executable ), 
'python.exe' ))
False

(This is from within Pythonwin, which has its executable elsewhere). 

It's a good idea to check and see if the file really does exist.  If it 
doesn't, either raise an error to tell the user to figure out what's 
wrong, or use the executable as given, (possibly checking/raising the 
error *only* if the executable is named pythonw and you can't find the 
python executable, though that would still have you running PythonWin in 
the above example (checking for "not named python" would be safer)).

Anywho, have fun,
Mike
