如何让python脚本在10秒后自动停止?

I am working on a project of my own that involves servos on a raspberry pi. I have them spinning when I execute the code but I'd prefer to have the python script kill itself after 10 seconds, rather then having to hit CTRL + C all the time. Is there a way to do this with this particular code?

我正在做一个我自己的项目，这个项目涉及到对树莓派的伺服系统。我在执行代码时让它们旋转，但我更希望python脚本在10秒后自动终止，而不是一直按CTRL + C。是否有一种方法可以使用这个特定的代码来实现这一点?

import RPi.GPIO as GPIO

import time

GPIO.setmode(GPIO.BOARD)

GPIO.setup(7,GPIO.OUT)

try:
                while True:
                        GPIO.output(7,1)
                        time.sleep(0.0015)
                        GPIO.output(7,0)

                        time.sleep(0.01)

except KeyboardInterrupt:
       print"Stopping Auto-Feeder"
       GPIO.cleanup()

Try something like the following:

试试以下的方法:

import RPi.GPIO as GPIO
import time


stop_time = time.time() + 10

GPIO.setmode(GPIO.BOARD)
GPIO.setup(7,GPIO.OUT)

try:
    while time.time() < stop_time:
            GPIO.output(7,1)
            time.sleep(0.0015)
            GPIO.output(7,0)

            time.sleep(0.01)

except KeyboardInterrupt:
    pass

print"Stopping Auto-Feeder"
GPIO.cleanup()
