+* Welcome
+
+I'm completing the Advent of Code puzzles and storing my answers here to compare with friends & family.  I'm starting in 2021 and using it to learn Python.  Hopefully it looks better further into the month as I learn more features!

+Since there are two parts to each question, my code is saved in the state it was at the time I discovered the first answer as `main.py`.  Logically, `main2.py` is the state of the code after solving the second half; sometimes it will still contain the solution for the first half (day 6, for example), while other times it'll be a conversion of `main.py` in order to solve the second half (day 4, for example).  **Not all days are refactored!**
