WARNING: This program has an error that we need to debug.

You can use a comma between strings and variables to output them without having to cast each value to a string.

• Click Run and enter a number as input. Read the error message that appears.
• "cannot concatenate str and int..." is an error that we have solved before by casting numbers using str().
• This time, fix the error by replacing the plus sign with a comma! This avoids needing to cast to a string.
