On Python 3.6+, use a formatted string literal (they're called f-strings: f"{2+2}" produces "4") with an if statement:

print(f"Shut the door{'s' if abs(num_doors) != 1 else ''}.")

You can't use backslashes to escape quotes in the expression part of an f-string so you have to mix double " and single ' quotes. (You can still use backslashes in the outer part of an f-string, eg. f'{2}\n' is fine)
