An actual complete code though?

While creating the error handling with the number of tickets being over the total, we lose the functionality of the error communication for a user entering a string for the number of tickets requested. It returns this"We ran into an issue. invalid literal for int() with base 10: 'five'. Please try again". Can we see a complete code that can handle both errors and not return "invalid literal for int() with base 10: 'five'. " but return something that says "Please use(enter) a whole number." or something like that.

That would be a complete functional program, IMO.

To get a more a "friendly" message than the built-in error text, you could check if the exception string contains the standard text and issue your own instead:

    except ValueError as err:
        # check for the "unfriendly" standard message
        if "base 10" in str(err):
            # then do NOT include the standard text in output
            print("Oh no! That's not a valid entry! Please use(enter) a whole number.")
        else:
            # Include the error text in the output
            print(f"Oh no, we ran into an issue. {err}. Please try again.")
