Python 代码无法与raspberry pi一起工作时遇到问题

按下按钮时，LED不会熄灭 while循环有问题吗？

更多详细信息更多详细信息我认为问题在于：

enter code here
led = LED(17)
led.off()

player_1 = Button(2)
player_2 = Button(3)

time = random.uniform(2, 5)
sleep(time)
led.on()
twoscore = 0
onescore = 0

restart = True

while restart == True:
    restart = False
    if player_1.is_pressed:
        onescore += 1
        print("player one score: " + str(onescore))
        led.off()
        restart = True
    if player_2.is_pressed:
        twoscore += 1
        print("player two score: " + str(twoscore))
        led.off()
        restart = True

Restart设置为False，然后代码在第一次迭代后立即退出循环

尝试以下方法：

while restart == True:
    restart = False

让我知道这是否有效

更好的是你可以写：

restart = True

while restart == True:
    if player_1.is_pressed:
        onescore += 1
        print("player one score: " + str(onescore))
        led.off()
        restart = False
    if player_2.is_pressed:
        twoscore += 1
        print("player two score: " + str(twoscore))
        led.off()
        restart = False

这就是您希望发生的事情吗？

现在就去试试，谢谢！对于第二个，我不想结束代码，而是制作一个评分系统。中断是结束代码还是结束while循环？它只是结束while循环-它“中断”了循环

while True:
    if player_1.is_pressed:
        onescore += 1
        print("player one score: " + str(onescore))
        led.off()
        break
    if player_2.is_pressed:
        twoscore += 1
        print("player two score: " + str(twoscore))
        led.off()
        break
