rule 5: one code enters, 7 codes leave
okay yeah so
p1 part 1 submitted, runs fine. part 2 says "wrong answer for you but right for someone else". doing a debug-print-everything run on the intermediate stages of the data after my regex all seems correct, but it's also 23h50 and it's been a looooong week. so I guess I'll take a look a fresh look at that one in the morning over coffee
part1, badly:
spoiler
import re pattern = '\d' cmp = re.compile(pattern) # extremely lazy, of the ungood kind datapath = 'data' lines = open(datapath, 'r').read().split('\n') candidates = [] values = [] for l in lines: if l != '': r = cmp.findall(l) candidates.append(r) values.append(int(''.join([r[0], r[-1]]))) print(candidates) print(values) print(sum(values))(I really wasn't kidding about the badly)
part2:
spoiler
missed the
eightwocasechanges:
mapping = {...} # name/int pairs pattern = f'(?=(\d|{"|".join(mapping.keys())}))' lines = open(datapath, 'r').read().split('\n').remove('') values = [] for l in lines: r = cmp.findall(l) equivs = [str(mapping.get(x, x)) for x in r] head, tail = [equivs[0], equivs[-1]] values.append(int(f"{head}{tail}")) print(sum(values))
