[Tutor] Python GPIO Code Help Needed

I have been working on a piece of code that I got from another tutorial. The code polls the GPIO pins on a Raspberry Pi. When it detects a switch being flipped, it plays a corresponding audio file. My problem is, if the switch remains flipped, the audio repeats again and again. What I would like
