Can prompt be a non-string?

No, the prompt parameter in the input() function must be a string. If you provide a non-string type (like an integer or a list), Python will raise a TypeError.

If you want to use a non-string type as a prompt, you should convert it to a string first using the str() function. For example:

number = 42
user_input = input(str(number))  # This will display "42" as the prompt
