What is wrong with my code to tell Python the value of my dice?

Below is my code. This is basically a petals around the rose thing im doing. If youre not familiar with this game its basically predicting the value of the roll of x amount of dices, in which dice with values 1,2,4,6 = 0 and dice with values 3 = 2 and dice with values 5 = 4 Here is my code.

 die1 = random.randint(1,6)
    die2 = random.randint(1,6)
    die3 = random.randint(1,6)
    die4 = random.randint(1,6)
    die5 = random.randint(1,6)
    result = display_dice(die1, die2, die3, die4, die5)
    roll_guess = int(input("please enter your guess for the roll:"))
    def dicevalue(die1):

        if die1 == 1 or die1 == 2 or die1 == 4 or die1 == 6:
            die1 == 0
        elif die1 == 3:
            die1 == 2
        elif die1 ==5:
            die1 == 4
        return die1
print(dicevalue(die1))

I also tried this and I got an error

for values in die1:
    if die1 == 1 or die1 == 2 or die1 == 4 or die1 == 6:
        die1 == 0
    elif die1 == 3:
        die1 == 2
    elif die1 ==5:
        die1 == 4

as you can see, I would like to summarise this code in terms of dice[i] to calculate all of them but I dont know how to. So i took the long approach to tell python what I just told you in the first paragraph. I am new to python so if the mistakes looks stupid please excuse my stupidity. thanksss
