elif语句不起作用

Question

对此我感到很抱歉，但是我是一个完整的初学者，无论我尝试什么，都出问题了。 谁能给我一个关于我的elif语句出了什么问题的小小的想法，以便我继续下去？ （我也知道在0％处当前存在1％的错误，这只是在测试理论）

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)

Answer 1

elif需要一个条件，就像if语句一样。 如果要无条件阻止，请使用else ：

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)
else:
    add =  add = (stampduty*one/100.0)
    addamount = stampduty + add
    print("Stamp Duty percent 0% \nyour stamp duty amount is", addamount)

也许您应该使用else代替elif 。 在elif ，就像if你需要传递的条件。
