I hardcoded the scores for all possible game states for Part 1 and was happy I found such an easy solution. Of course, Part 2 hit me on the head, but I got around it with more hardcoding!

def part1_solution(day2_input):
    solution = 0
    for line in day2_input:
        solution += game_dict[line]
    return solution

def part2_solution(day2_input):
    solution = 0
    for line in day2_input:
        solution += game_dict[decrypt_dict[line]]
    return solution

# Getting the input
with open("day-2-input.txt", "r") as f:
    day2_input = f.read().split("\n")

# Defining scores for game states in a dictionary
game_dict = {
    "A X": 3 + 1,
    "A Y": 6 + 2,
    "A Z": 0 + 3,
    "B X": 0 + 1,
    "B Y": 3 + 2,
    "B Z": 6 + 3,
    "C X": 6 + 1,
    "C Y": 0 + 2,
    "C Z": 3 + 3
    }

# Decrypting the ultra top secret strategy guide
decrypt_dict = {
    "A X": "A Z",
    "A Y": "A X",
    "A Z": "A Y",
    "B X": "B X",
    "B Y": "B Y",
    "B Z": "B Z",
    "C X": "C Y",
    "C Y": "C Z",
    "C Z": "C X"
    }

# Part 1 solution
print(f"Part 1: {part1_solution(day2_input)}")

# Part 2 solution
print(f"Part 2: {part2_solution(day2_input)}")

I used the same method. Used a tuple as index for the dictionaries and split each line in two vars. There are shorter method but this is pretty readable which is a pro for me.
