Need help converting string to int

[snippsat]

You don't convert first num to integer in function.
You convert with result,but never use it.

num = input("Enter a number to CUBE: ")
result = int(num)

def cube():
    print(result * result * result)

cube()

But should not write as this function should take argument in like this,can also do convert on input().
Then it will be like this,now it clear that cube need a argument num in.

def cube(num):
    print(num * num * num)

if __name__ == '__main__':
    num = int(input("Enter a number to CUBE: "))
    cube(num)
