Iteration While

while.py

i = 1
while i <= 6:
    i = i + 1
    print(i)




 


break.py


i = 1
while i <= 6:
    i = i + 1
    print(i)
    if i == 3:
        break #rejects all remaining statements in current iteration of loop, and (also) exits the loop

Using a WHILE loop:

    

  1. Count up from 1 to 10.

    2. 

  2. Count backwards from 10 to 1, and then print "blastoff" on the next line.

    3. 

  3. Count backwards from 50 to 1. Skip the number 40 entirely. Break the count at number 20.

    4. 

  4. Challenge:print a list of even numbers between 40 to 0 (counting down). Only print the even numbers.

    5. 

  5. Challenge:Develop a game called "Unmatch", where the aim is to count how many times 2 dice can be rolled without matching. 

    
    To play, 2 dice are rolled using random.randint(1,6), and if the rolls don't match, the score can be increased by +1. If the rolls do match, the score gets reset to 0.

    
    Try and keep a high score to see how many "unmatches" you can get in a row.
