In this series, I'll share my progress with the 2023 version of Advent of Code.
Check the first post for a short intro to this series.

December 2nd
The puzzle of day 2 was not so hard. The one from yesterday made me a bit nervous for what's to come, but it seems the Elves gave me a break today 😅
My pitfall for this puzzle: Not really any, programming the solution was pretty straightforward.
Solution here, do not click if you want to solve the puzzle first yourself
#!/usr/bin/env python3
valid_games = []
game_powers = []
def is_valid_draw(marbles):
for marble in marbles:
[count, color] = marble.split(' ')
if (color == 'red' and int(count) > 12) or \
(color == 'green' and int(count) > 13) or \
(color == 'blue' and int(count) > 14):
return False
return True
def is_valid_game(games):
for game in games:
marbles = game.split(', ')
if not is_valid_draw(marbles):
return False
return True
def game_power(game_marbles):
red = 0
green = 0
blue = 0
for marbles in game_marbles:
for marble in marbles:
[count, color] = marble.split(' ')
if (color == 'red' and int(count) > red):
red = int(count)
if (color == 'green' and int(count) > green):
green = int(count)
if (color == 'blue' and int(count) > blue):
blue = int(count)
return red * green * blue
with open('input.txt') as infile:
lines = infile.readlines()
for line in lines:
[game_id, all_games] = line.strip().split(': ')
game_number = int(game_id.split(' ')[1])
games = all_games.split('; ')
if is_valid_game(games):
valid_games.append(game_number)
game_marbles = [game.split(', ') for game in games]
game_powers.append(game_power(game_marbles))
print(sum(valid_games))
print(sum(game_powers))
That's it! See you again tomorrow!
