Exercises

September 18 - September 22, 2006

To ensure that you receive appropriate laboratory credit, for each exercise make sure that I have looked at your source code and seen a demonstration of your working program.
  1. Write a while loop that prints all of the even numbers between 1 and 100.
    Create two versions of this loop, one that uses an if statement and one that does not.
  2. Write a program that uses the module random to select a random number between 1 and 10 (example below) and asks the user to repeatedly enter a number until he/she has guessed the random number.
    #import the module random
    import random
    #call the randint function passing in the range
    num = random.randint(1, 10)
  3. Design a program which prompts the user for a number of rows between 0 and 10 and prints the following pattern:
    ****
    ***
    **
    *
  4. Design a program which prompts the user for a number of rows between 0 and 10 and prints the following pattern:
       *
      * *
     * * *
    * * * *
