1 Note that we have to import java.util.InputMismatchException in order to use the InputMismatchException class.  We are using a while loop to ask the user the same question until the user enters the correct input.
All programming languages, including Python, feature what are known as loops. These processes perform certain actions an indefinite number of times until a particular parameter is met. If you were constructing a video game, for instance, you might ask the user if he or she wants to play again after completing a round.econd_Number = input(to this: ). print First_Number, +, Second_Number, =, First_Number + Second_Number. Add an if construct that compares some value to a parameter. If you were trying to build a program that counts from 1 to 2000, for instance, you might check whether the number has reached 2000 yet.
