之前，我曾就同一段代码问过类似的问题，但我再次发现自己陷于困境。特别是在生成包含两个字母，两个数字，然后两个字母的车牌时。我希望这个问题不会重复出现，但是在这种情况下，我非常想做什么，这是到目前为止的代码，希望您能确定我要去哪里：

from datetime import date, datetime, time, timedelta
import time, string
from random import uniform, random

def timeDelta():
    print("Average Speed Checker")
    start = (input("Car has passed Cam1: "))

        print(camInput1)
        print("Car is travelling...")
        time.sleep(1)
        print("Car is travelling...")
        time.sleep(1)
        print("Car has passed cam2")
        camInput2 = camInput1 + timedelta(seconds = uniform(5, 10))
        timeDelta = camInput2 - camInput1
        distance = 200
        duration = timeDelta.total_seconds()
        print("Time Delta …
