In a Python program, the if statement is how you perform this sort of decision-making. It allows for conditional execution of a statement or group of statements based on the value of an expression.

Let’s consider a more elaborate example. The Python program below asks the user 3 math questions. We go through those questions with a loop. Inside that loop we have an if/else statement evaluate the answers. This way we get a mini quiz. The program’s complete code is: questions = ["What's 4 times 3? ", "What's 60 - 6?
