Wonderful!

Yes. You are using the ‘input’ function, built in to Python 3 <URL:https://docs.python.org/3/library/functions.html#input>. Read the documentation for that function; when successful, it returns text (“a string”). If you want an integer, you will need to explicitly tell Python to convert the text to an integer value. To create a new object, a general way is to use the type as a constructor. The type you want is ‘int’, so use that as the constructor, and you will (if it succeeds) get a new integer as the return value:: response = input("Enter inches here: ") inches = int(response) You will also need to learn about handling conversion errors: Try entering something that is *not* a representation of an integer and see what happens. How to handle the error is up to you. -- \ “Yesterday I parked my car in a tow-away zone.
