808 drum machine

In circuitplaygroundexpress python, I finished this project and it isn’t working. Here is my code:

import audioio
import touchio
import board
import time

from digitalio import DigitalInOut, Direction

bpm = 120

spkrenable = DigitalInOut(board.SPEAKER_ENABLE)
spkrenable.direction = Direction.OUTPUT
spkrenable.value = True

touch1 = touchio.TouchIn(board.A1)
touch2 = touchio.TouchIn(board.A2)
touch3 = touchio.TouchIn(board.A3)
touch4 = touchio.TouchIn(board.A4)
touch5 = touchio.TouchIn(board.A5)
touch6 = touchio.TouchIn(board.A6)
touch7 = touchio.TouchIn(board.A7)

audiofiles = [“bd_tek.wav”, “elec_hi_snare.wav”, “elec_blip2.wav”, “bd_zome.wave”, “bass_hit_c.wav”, “drum_cowbell.wav” ]

a = audioio.AudioOut(board.A0)

def play_file(filename):
f = open(filename, “rb”)
wave = audioio.WaveFile(f)
a.play(wave)
time.sleep(bpm/960)

while True:
for i in range(7):
if touchPad[i].value:
play_file(audiofiles[i])

please get back to me as soon as possible. Thanks
