我为此感到抱歉,但我是一个完全的初学者,无论我尝试什么,都会出错.任何人都可以给我一个小小的想法,我的elif声明出了什么问题,所以我可以坚持下去吗？(我也知道当前0%的错误是1%,只是测试理论)

one = (1)
three = (2)
four = (4)
five = (5)
seven = (7)

stampduty = int(input("Enter amount of residential property"))

if stampduty >= 1 and stampduty<=125000:
    add = (stampduty*one/100.0)
    addamount = stampduty + add
    print("Stamp Duty percent 0% \nyour stamp duty amount is", addamount)
elif:
    add =  add = (stampduty*one/100.0)
    addamount = stampduty + add
    print("Stamp Duty percent 0% \nyour stamp duty amount is", addamount)
