程序未打印

Question

我写了这个程序，但是当我打印它时它没有执行:

age= int(input("How old is your dog?"))
if age>0:

print("Please input positive number")
elif age<=2:

dage= age*10.5
else age>2:

dage=21+((age-2)*4)
print("The dog is", dage, "years old")
print(age)

要使它运行，我缺少什么?

Answer 1

我认为你想要取消缩进条件语句。我认为你的条件语句也需要一些工作-我已经更新了一点。见下文.

试

age = int(input("How old is your dog?" ))
dage = 0
if age < 0:
print("Please input positive number")
elif age <= 2:
dage = age*10.5
else:
dage = 21+((age-2)*4)
print("The dog is", dage, "years old")
print("age", age)
