I'd probably use metaclasses if I had the kind of problem where code generation could actually help. The last time I saw a project using code generation where I thought that it ought have to used metaclasses was a tool to generate python code from swagger descriptions. Django's ORM is a good example where metaclasses were used to good effect (there are very few of those). In general I'm extremely suspicious of anybody who claims to have the kind of problem that requires either metaclasses or code generation would help though. It is suitable only for problems that are very, very, very abstract (e.g. like an ORM or REST API interaction framework). In 90% of cases I've seen the person attempting to use it vastly overgeneralized the problem that they actually had in an attempt to prepare for future problems never arose. In the process of doing that they then created a code clusterfuck that was hellishly hard to understand and debug (and in some cases I was left to clean up the mess). It wasn't simple and it can't, intrinsically, ever be simple (there is some language theory behind this). I could be convinced otherwise by describing your problem, but right now I'm 80% convinced that what you have described is an XY problem and that you're attempting to do this because you overgeneralized your problem. If you describe the actual problem you're solving it might help. More on reddit.com

This sounds like an X-Y question, I think you should describe your larger goal rather than asking how to implement this specific solution. Generating code is usually a bad idea and usually not necessary. More on reddit.com

Hey folks! Sharing my Python project template. I've been using (and improving) it since 2016, but this is the first year it's an actual GitHub template. It handles: creating stub files each day reading your test & live inputs parsing a few pre-defined input types (string-per-line, int, etc) running your solution, profiling, debugging, and a few more niceties. storing any helper functions you write It doesn't do any automatic downloading or submitting, but makes it easy to do those yourself; I personally like a more simplistic approach. It also includes a minimal linting/formatting setup! I'll also be sharing step-by-step solutions (using the above) each day if anyone gets stuck. My goal is that anyone with programming experience can understand the solution to literally every AoC puzzle, so they really break each problem down. I've got solutions for every puzzle going back to 2020. Check it all out here: https://advent-of-code.xavd.id/ More on reddit.com
