重新启动自己的程序？

Question

from datetime import datetime 
platenumber = input("Enter the license plate number:") 
start = input("Press enter to start.") 
starttime =(datetime.now()) 
stop = input("Press enter to stop.") 
stoptime =(datetime.now()) 
dist1 = 0 
dist2 = input("Enter the distance of the road in metres:") 

time = ((stoptime - starttime).total_seconds()) 
print((time),"is the time in seconds.") 
distance = int(dist2) - dist1 
print((distance),"is the the distance in metres.") 
speed = float(distance)//time 
print((speed),"is the speed of the vehicle in m/s.") 

我想在使用它之后重新启动程序，以便我可以检查车辆的速度不止一次。

请帮我完成代码，以便我可以自行重新启动代码并检查多个车辆的速度。

Answer 1

使用while循环。

while True: 
    # Do your code 

底：

again = input("Do this again?") 
    again = again.lower() 
    if again.startswith('n'): 
     break # Get out of the loop
