Algorithms For Dummies

DisplayMulti('Hello', 'Cont', 'Goodbye', 'Break', 'Last') and press Enter. Notice 

that the words 

Cont

 and 

Break

 don’t appear in the output because they’re key-

words. In addition, the word 

Last

 doesn’t appear in the output because the 

for

 

loop ends before this word is processed.

Using the while statement

The 

while

 loop statement continues to perform tasks until such time that a con-

dition is no longer true. As with the 

for

 statement, the 

while

 statement supports 

both the 

continue

 and 

break

 keywords for ending the loop prematurely. To see 

how this works, open a copy of IPython and type the following code:

def SecretNumber():

   GotIt = False

   while GotIt == False:

      One = int(input("Type a number between 1 and 10: "))

      Two = int(input("Type a number between 1 and 10: "))

  

      if (One >= 1) and (One <= 10):

         if (Two >= 1) and (Two <= 10):

            print('Secret number is: ' 

+ str(One * Two))

            GotIt = True

            continue

         else:

            print("Incorrect second value!")

      else:

         print("Incorrect first value!")

      print("Try again!")
