You can do something like

def pathToExecutable():
    dir, file = os.path.split(sys.executable)
    if file == "my application name":
        return dir
    dir, file = os.path.split(sys.argv[0])
    return dir

If you want a more general version to handle any application name, then 
you need to deal with determining whether the app is being run from a 
script or has been frozen (with py2exe or py2app or freeze or ...)
