audio object string

The following script contains a function which attempts to play
an audio file which is passed as
an argument. Before calling the function I want to construct the
name of the audio object by concatenating character strings, but
it doesn't work. Can you tell me the correct way to do this?

Code:

from viz import *



go()



sound1 = add('boing!.wav')



def playit(snd):

        snd.play()



num = 1

s = 'sound'+str(num)



playit(s)

Are you trying to look up a Python object by its name? The following will look up the name in the current global variable scope and play the sound if it exists:

Code:

def playit(snd):

        soundObject = globals().get(snd,None)

        if soundObject is not None:

                soundObject.play()
