How to optionally repeat a program in python

Question

I\'m learning python and had a quick question.

I have to write a code to find the cube root, which I\'ve done. I want to give the user the option of calculating an

Answer 1

There is also another way, similar to @xgord answer. Use a a while loop. What i wrote is longer but simpler to me

repeat = False
while not repeat:
      # game code

play = input("Play again? (y/n)")
    if play == "y":
        repetition = False
    else:
        exit()

Answer 2

As an alternative to the function route, you could do it in a while loop, though it would be cleaner to use functions. You could do:

choice = 'y'
while choice.lower() == 'y':
    #code for the game
    choice = raw_input ('run again? (y/n)')

Answer 3

You can put all inside a function:

def my_func():
   x = int(raw_input('Enter an integer:   '))

   ## start guessing with 0 
   ans = 0

   while ans*ans*ans < abs(x):
       ans = ans + 1
       print 'current guess =', ans

   print 'last guess = ', ans
   print 'ans*ans*ans = ', ans*ans*ans


   ##if its a perfect cube

   if ans*ans*ans == abs(x):
   ## perfect, but negative
       if x<0:
             ans = -ans
       print 'Cube root of ' + str(x)+ ' is ' + str(ans)

   ## If its not a cube at all    
   else:
       print x, 'is not a perfect cube'



   ## Now to start a new calculation
   again = raw_input('Find another perfect cube? (Y/N)')

   if again == "N":
       quit
   if again == "Y":
       my_func()

if __name__ == '__main__':
    my_func()
