Vet mooi notebook van Bas

Laten we beginnen met de imports

import re 

Puzzel 1

Deel 1

f = open('data/puzzle_1.txt', 'r')
total = 0
for line in f:
    digit_1 = re.search('(\d)', line).group()
    digit_2 = re.search('(?:\d)(?!.*\d)', line).group()
    total += int(digit_1+digit_2)
total

Deel 2

l = ['one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine']
digits = '|'+'|'.join(l)
f = open('data/puzzle_1.txt', 'r')
total = 0
for line in f:
    string_digits = re.findall('(?=(\d'+digits+'))', line)
    string_digits = [digit if (digit not in l) else str(l.index(digit)+1) for digit in string_digits]
    total += int(string_digits[0] + string_digits[-1])
total

Puzzel 2

data = open('data/puzzle_2.txt', 'r').readlines()
