Level 3

Now type the code into the IDE below and run the program to see the code’s output.

Study the code below: import time for x in range(10): print(10-x) time.sleep(1) print(“Blast Off!”)

Create a program that takes a number and prints all even numbers from 2 up to and including that number if it’s even, using a while loop.

Write a program that asks for a number and then counts down from that number to 1, printing each number on a new line.

Create a program which asks for a number and then prints a 1, then a 2, then a 3 up to the inputted number.

Write a program that continuously accepts integer values from the user and adds them to a total sum. The loop stops and the sum is printed when the user enters the value -1.

Modify the code above so that it matches the code below: x = 0 total = 0 while x != 10: x = int(input(“Enter a number”)) total = x + total print(“Your final total is “, total) Below, explain what the code is doing and how it words line by line.

Using the python IDE below, investigate the following and explain your findings in the text area below. 1. What happens if you remove int() from the input statement? Explain the result. 2. What happens if you replace the ‘!’ sign with another ‘=’ sign? Explain the result.

Now type the code into the IDE below and run the program to see the code’s output.

Study the code below: x = 0 while x != 10: x = int(input(“Enter a number: “)) print(“You found the stopping value!”)
