When I set up my object mappings with SQLalchemy, everything works well enough. It even creates the tables for me if they don't exist. However, if I decide to add/remove columns (aka fields) from ...
Since you didn't mention memory, I'll assume O(N^2) is acceptable. Setup pseudocode: for every p1, p2: ln = line(p1, p2) points_on_line[ln.m, ln.c] += [p1, p2] If there are at least ...
Dependency conflicts are the problem pipx aims to solve, in the context of installing CLI programs. When you install a Python package, by default pip will also install their dependent packages so ...
Is there a Python serialization format that has capabilities similar to Pickle, but is text based? The problem I always have with pickle is that it's binary, so I can't manually view or edit the d...
Everything you put on the line with def is global (global to the file, not as in the global keyword), so the (initially empty) list you create with param=[] persists and gets reused between calls t...
Hashing is lossy compression. You can't recover the input of a hash from the result. This would obviously not work as an encryption. How would you decrypt it, if half the message is destroyed :) ...
You could just move the files to a new folder and open that :) Alright alright here's a serious answer: I noticed that VSC automatically dereferences symlinks. So if you create a temporary new fol...
I have a Python program like this: done = False while u and not done: i = u.pop() print(f"Processing {i}") do_big_task(i) finish_up() Since this takes a long time, the user m...
Beginner questions are not a "huge problem" for StackOverflow. They are the main reason SO got big at all. During what I would call its "peak", the joke going around was that the best documentation...
Much of this is already covered in various sources like https://docs.python.org/3/howto/unicode.html. Although there are issues with relying on links, I figure official documentation is probably fa...
A page is very slow and laggy in Firefox. I am certain it's one of the many Javascripts slowing it down. Out of curiosity, I'd like to figure out which script is creating the heaviest load. Note t...
The reason this practice exists is because CIs suck. The frameworks/services themselves suck, and the way people write the configs also suck, and the two combine to create a mega-suck. A CI is sup...
Suppose someone has the requisite knowledge and skillset to contribute to a FOSS project, they have the free time to do so and they are aware of the project. Yet, they decide not to contribute. Thi...
In the last few months, AI has advanced considerably, notably in the area of generating images. We now have powerful models like DALL-E, Stable Diffusion, etc. These are quite competent at generati...
We have special features/sections on Codidact, so maybe this is a nice use for them. What if we had a section named something like "clinic" or "case study" or "debugging"? (name suggestions welcom...
tl;dr: When a question is unclear, don't close right away, especially if it's possible to discern what they are trying to ask. Instead, use comments and edit suggestions to work with the asker and ...
