Hopefully not - and nothing forces you into adopting the common 
convention !-) But it's a fact that Python relies heavily on naming 
conventions, and that it greatly helps readability.

DEVICE_TYPES = {
   'PSP' : Psp,
   'Power Supply' : Pwr,
}

def get_device(device_type):
     cls = DEVICE_TYPES.get(device_type, None)
     if cls is not None:
        return cls()
     # implicitly returns None, which may or not be a GoodThing(tm)
