Python Tip #241 (of 365):
Let dataclasses write your dunder methods. 🧵
The dataclass decorator writes __init__, __repr__, and __eq__ for you:
from dataclasses import dataclass

much easier than I thought

I just completed "Warehouse Woes" - Day 15 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/15
Lazily(?) got through this while fighting post-vaccine symptoms. Part 2 is such a simple change, but handling vertical pushes changes the approach dramatically.
(I also love dataclass!)

Maybe it did not need to be a dataclass, but I'm pretty proud of writing my first python class for the bits I needed to code today after taking some fun time over the holiday break to learn all about python classes because I am that geeky.

Easily add ordering to #Python dataclasses 💡
Dataclasses aren't orderable by default. Add `order=True` to auto-generate comparison methods like __lt__ & __gt__.
This makes sorting/compare tasks seamless! Check out an example 👇

For every class you make, either:
1. create a __init__ method
2. use a tool (like the dataclass decorator) to create a __init__ method
3. inherit from a class that has a useful __init__ method method.

Apparently in Python's dataclasses any member not set via the constructor gets ignored in equality checks. Both asserts pass in the code included code snippet. I put this example to a gist of it so I can reference it in the future: gist.github.com/pekkavaa/4a1...
