Write a function that simulates three cubic dice rolls.

Hi, I want to write a function that simulates three cubic dice rolls. In case the same number is drawn twice in a row, display "Double!" Example: Input: random () Output: 2 5 5 Double!

I already wrote the randomizing function... but I am not sure how to finish it... Thanks in advance for your help!

import random
i=0
list =[]
def randomizer():
  for i in range (3):
   i+=1
   list.append(random.randrange(0,6))

  return(list)

print(randomizer())

Now you need to evaluate the list for duplicate occurrences in a row of the number. This would require checking the first and second number, and then check the second and third number.

Maybe something like this?

import random

def hand_randomizer(number_of_dice=3, number_of_sides=6):
    """randomize a hand"""
    # optionally specify number of dice, and number of sides per dice
    # default is 3 for number_of_dice
    # default is 6-sided dice
    hand = []
    for i in range(number_of_dice):
        hand.append(random.randint(1,number_of_sides))
    return(hand)

def match_count(value, hand):
    """return how many dice match the give value"""
    count = 0
    for die in hand:
        if die == value:
            count += 1
    return count

def max_matching_values(hand):
    """return maximum number of matching dice"""
    for count in range(len(hand),0,-1):
        for die in hand:
            if match_count(die, hand) == count:
                return count
    return 0

# create a hand
hand = hand_randomizer()
# count maximum number of matching dice
max_match = max_matching_values(hand)

output = str(hand)
if max_match == 2:
    output += " Double!"
if max_match == 3:
    output += " Three-of-a-kind!"

print(output)

Example output of three selected runs

[4, 1, 5]
[1, 1, 6] Double!
[4, 4, 4] Three-of-kind!
