My first Python program! Small stuff, but I see bigger things on the horizon

        elif playstatus == 3:
            return 'Winamp is paused.'
        else:
            return 'Unrecognized Winamp status.'


usage:

import winamp
winamp = winamp.winamp()
winamp.play()

A little bit of advice:

- Naming conventions: CamelCase class names, lowercase_underscored method, function, and variable names
- Properties: it might be a little bit nicer to say winamp.volume = 100 rather than winamp.setvol(100). A simple example of properties should serve you nicely:

class TestProperties(object): # must extend object, new-style classes
    def get_prop(self):
        return "get_prop()"
    def set_prop(self, value):
        print "setting",value
    prop = property(get_prop, set_prop)


Also, the convention is to use "self" instead of "me", but it doesn't really matter.
