Vet mooi notebook van Bas

Laten we beginnen met de imports

import re 

Puzzel 1

Deel 1

f = open('data/puzzle_1.txt', 'r')
digits = [re.findall('\d', line) for line in f]
numbers = [str(digit[0]) + str(digit[-1]) for digit in digits]
numbers = [int(x) for x in numbers]
print(sum(numbers))

Deel 2

f = open('data/puzzle_1.txt', 'r')
l = ['one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine']
digits = [re.findall('(?=(\d|'+'|'.join(l)+'))', line) for line in f]
numbers = [[digit[0],digit[-1]] for digit in digits]
listing = []
for number_pair in numbers:
    number_string = ""
    for number in number_pair:
        if number in l:
            number_string += str(l.index(number) + 1)
        else:
            number_string += str(number)
    listing.append(int(number_string))

sum(listing)

Puzzel 2

Deel 1 & 2 tegelijk, oeps

f = open('data/puzzle_2.txt', 'r')
rows = []
red = 12
green = 13
blue = 14
for x in f:
    row = {}
    row['id'], row['content'] = x.split(':')
    row['id'] = int(re.findall('\d+', row['id'])[0])
    row['counts'] = row['content'].split(';')
    listing = []
    maxes = {'red': 0, 'green': 0, 'blue': 0}
    for count in row['counts']:
        numbers = re.findall('\d+', count)
        colors = re.findall('red|blue|green', count)
        for test_color, test_number in zip(colors, numbers):
            if maxes[test_color] < int(test_number):
                maxes[test_color] = int(test_number)
        listing.append(dict(zip(colors, numbers)))
    row['maxes'] = maxes
    row['counts'] = listing
    rows.append(row)

            
        
    
    

Naja hier pas de output

count = 0
count_2 = 0
for row in rows:
    maxes = row['maxes']
    count_2 += maxes['red'] * maxes['blue'] * maxes['green']
    if red >= maxes['red'] and blue >= maxes['blue'] and green >= maxes['green']:
        count += row['id']
print(count)
print(count_2)
