Repeating an algorithm as many times as the user requires (PYTHON 3.3.2 GUI) -

i'm trying repeat algorithm , use values in code, please help!!!

import random

def dice_roll(number):     if number == 12:         number = random.randint(1,12)         print(number)         return(number)     elif number == 6:          number = random.randint(1,12)          print(number)          return(number)     else:         number == 4         number = random.randint(1,12)         print(number)         return(number) 

dice_roll(int(input("which dice roll? --> ")))

is this?

import random  def dice_roll(number):     if number == 12:         number = random.randint(1,12)         print(number)         return(number)     elif number == 6:         number = random.randint(1,12)         print(number)         return(number)     else:         number == 4         number = random.randint(1,12)         print(number)         return(number)  while true:    dice_roll(int(input("which dice roll? --> ")))    dorepeat=input('go again?')    if dorepeat == 'no':       break 

edit:

 raw_input() renamed input(). 

you can use "input()" in 3.x, older versions, this:

dorepeat=eval(input('go again?'))
