I wanted to use your solution as reference for the 2021 day 13 puzzle, but when I execute I get the following error:

Traceback (most recent call last):
  File "C:/Users/jcroce/develops/c/advent_code_21/p13e/day13p2.py", line 3, in <module>
    t, b = data.split("\r\n\r\n")
           ^^^^
NameError: name 'data' is not defined

If we check the code is clear that the data has not been set. By the look of the code (and testing it) adding the following two lines at the beginning make it work:

import sys
data = sys.stdin.read()

The split on "\r\n\r\n" does not work for me, changing it to "\n\n" makes it work:

t, b = data.split("\n\n")

Anyway, thank you so much for providing such precise solutions, it helps a lot!

How do you run the challenges ?

I am new to python (learning it) and I find your examples interesting since I am also resolving the challenges on my side using node.js.

I saw the two main files at the root of your repo :

• prefix.py seems to consumes the stdin to build the data variable
• solver.py looks like it contains a custom built python interpreter (!)

Since your solutions rely on variables that are not declared (such as data in day1p1.py), I suspect that you somehow combine the calls (something like python solver.py input.txt 2021/day1p1.py) but I have to admit I am lost...
