速度传感器程序，循环，python3，A

Question

我需要能够循环这个代码的条件，如果用户想重复的程序，那么它必须循环。如果用户希望退出程序，则应显示所有超速行驶的车牌号。到目前为止，我得到的是：

import time
capturedtime=time.time()

speed_limit = 30
distance = 50

numberplates = []
newplate = ("Input number plate")

input("Press enter to start")
start_time = time.time()
input("Press enter to stop")
stop_time = time.time()
capturedtime = stop_time - start_time

print('Time taken: {:.2f} seconds'.format(capturedtime))
print('Distance: {:.2f}'.format(distance))
speed = distance / capturedtime
print('Speed: {:.2f}'.format(speed))

if speed > speed_limit:
    print("You were breaking the speed limit")
    numberplates.append(newplate)

Answer 1

如果我理解正确，您可以将所有代码放入while循环中，然后通过另一个input（）停止它。在

示例：

import time
exit = True
'''your variables'''
while(exit):
    '''your Code'''
    x = input("Enter 'y' if you want to exit.")
    if x.lower() == y:
        exit = False
        print("All speeding Cars:") # Print all the Cars!
        for plate in numberplates:
            print(plate)
