This Python module helps with converting Advent of Code ASCII art letters into plain characters. At the moment, it only supports 6-pixel-tall characters as seen in 2016 Day 8, 2019 Days 8 and 11, and 2021 Day 13.
Support for 10-pixel-tall characters (2018 Day 10) is coming soon.
Put simply, it converts this to ABC:
██ ███ ██
█ █ █ █ █ █
█ █ ███ █
████ █ █ █
█ █ █ █ █ █
█ █ ███ ██This module can be installed from PyPI:
$ pip install advent-of-code-ocrUsing this module is pretty easy. By default, this module recognizes # as a filled pixel and . as an empty pixel. However, you can change this using the fill_pixel and empty_pixel keywork arguments respectively.
from advent_of_code_ocr import convert_6
print(convert_6(".##.\n#..#\n#..#\n####\n#..#\n#..#"))
# A
print(convert_6(" $$ \n$ $\n$ $\n$$$$\n$ $\n$ $", fill_pixel="$", empty_pixel=" "))
# AYou can also convert data that you have in a NumPy array or a nested list:
from advent_of_code_ocr import convert_array_6
array = [
[0, 1, 1, 0, 0, 0, 1, 1, 0, 0, 0, 1, 1, 0],
[1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0, 1],
[1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0, 0],
[1, 1, 1, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0, 0],
[1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0, 1],
[1, 0, 0, 1, 0, 0, 1, 1, 0, 0, 0, 1, 1, 0],
]
print(convert_array_6(array, fill_pixel=1, empty_pixel=0))
