Using list instead of dictionary for organized results

I'm trying to get my code below working to have the results organized rather than random.

This is what's happening now.

sum = 9 count = 117
sum = 6 count = 142
sum = 3 count = 58
sum = 7 count = 172
sum = 8 count = 129
sum = 5 count = 109
sum = 4 count = 87
sum = 11 count = 53
sum = 12 count = 31
sum = 10 count = 72

And what I'm trying to achieve is

    sum = 1 count = 117
    sum = 2 count = 142
    sum = 3 count = 58
    sum = 4 count = 172
    sum = 5 count = 129
    sum = 6 count = 109
    sum = 7 count = 87
    sum = 8 count = 53
    sum = 12 count = 31

etc. While omitting any number that hasn't been rolled. I'd ideally like to use a list instead of a dictionary but any time I try it I get varying errors. Currently this outputs the amount but not in order.

    import random
    
    print("results")
    occurrences = []
    for i in range(1000):
        die1 = random.randint(1, 6)
        die2 = random.randint(1, 6)
        roll = die1 + die2
        current = occurrences[roll, ]
        occurrences[roll] = current + 1
    
    for roll, count in occurrences[]
        print(f"sum = {roll} count = {count}")
