python - 为什么 Eevee.wav 不能播放

Question

当两个键都被点击并且 PetHappyTF 为 1 时，我试图让 Eevee.wav 播放。任何时候我按 E 它都不会播放。我知道音频很好，因为当我删除第一个如果它有效时。所以...求救！

#importing stuff
from playsound import playsound
import keyboard
import speech_recognition
import pyttsx3
import pyaudio
import time

#data load
PetHappyTF = 1

#first bootup
playsound('Bootup.wav')

#Program
while True:
    def countdown(PetHappyCD):
        while PetHappyCD > 0:
            PetHappyCD -= 1
            time.sleep(1)
        PetHappyTF= 1    
            
            
if PetHappyTF == 1:
    if keyboard.is_pressed("E"): #Keystroke standing in for touch sensor. Eevee.wav standing in for Happy sound
        playsound('Eevee.wav')
        PetHappyTF = 0

seconds = 15
seconds = int(seconds)
countdown(seconds)
