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.

    return password


def part_2():

    password = [''] * 8
    ind = 0

    while any(p == '' for p in password):

        ind += 1
        
        inp = puzzle_input + str(ind)
        hashed = md5(inp.encode()).hexdigest()

        if hashed[:5] == '00000' and hashed[5].isdigit() and int(hashed[5]) < 8:
            if password[int(hashed[5])] == '':
                password[int(hashed[5])] = hashed[6]

    return ''.join(password)
