This is so janky but fuck it. I'm not aiming for efficiency, I'm aiming to get an answer. I am slightly intimidated by Part 2.

raw_input = open("input.txt", "r")
input = raw_input.read().splitlines()
raw_input.close()


def is_part(line, i):
    is_part = False
    start_line = line - 1
    end_line = line + 1
    if line == total_lines - 1:
        end_line -= 1
    elif line == 0:
        start_line += 1

    searching = True
    first_pass = True
    while searching and i >= 0:
        for line_index in range(start_line, end_line + 1):
            if not input[line_index][i].isdigit() and input[line_index][i] != ".":
                is_part = True
                searching = False

    return is_part


total_lines = len(input)

for line in range(total_lines):
    current_number = 0
    for i in range(line_width):
