Advent of Code Solutions

I have set myself a personal challenge to try and get up to date with advent of code, a set of programming challenges released each December.

Each day has 2 related problems, for a total of 50 problems per year. Each button below will show my code solving that problem. Green buttons where I have solved both problems of the day, orange where I have only solved the first one and red where I haven't solved either.

Both parts completed
from util.input import get_input
from hashlib import md5

def part_1():
    
    puzzle_input = get_input(2015, 4).strip()

    attempt = 0
    while True:
        md5_hash = md5(f'{puzzle_input}{attempt}'.encode()).hexdigest()
        if md5_hash.startswith('00000'):
            return attempt

        attempt += 1

def part_2():
    
    puzzle_input = get_input(2015, 4).strip()

    attempt = 0
    while True:
        md5_hash = md5(f'{puzzle_input}{attempt}'.encode()).hexdigest()
        if md5_hash.startswith('000000'):
            return attempt

        attempt += 1
