Mastering Immutable Python Strings

semantic winner ≠ policy winner Ran RISWIS Applied on a fresh machine (PowerShell, Python 3.12). Same system. Different query phrasing. → one returns pure semantic ranking → one triggers policy override RISWIS doesn’t force outcomes. It makes ranking decisions visible. can demo from GitHub https://lnkd.in/giw8HXCd

Here’s a tiny Python change that pays off fast. Python tip: use `@dataclass(slots=True)` for high-volume models. It removes per-instance `__dict__`, which usually means lower memory usage and slightly faster attribute access. Great for DTOs, parser outputs, event payloads, and cache objects where shape is fixed. Mini rule: if the object schema is stable, add `slots=True` by default. #Python #Performance #CodeQuality #SoftwareEngineering

Running Python checks inside Codex is fine until the main thread fills with uv, ruff, pytest, and ty logs—you lose context and still have to decode what mattered. I wrapped that work in a subagent-backed skill so checks run off-thread and return a short pass / warn / fail report, on top of the uv-first repo instructions I already use.

I’ve found CLIs to be more effective and consistent than MCPs. I build CLIs in Python and GO for my Claude skills and Codex Skills. When I use a publicly available skill that uses an MCP, I convert them to CLIs and it’s faster and superior.

Use dt.day_of_week to get the day number from a #Python #Pandas datetime series. But is 0 Sunday or Monday? Or not used at all? Better: Use the day_name method: df['x'].dt.day_name() Good news: It returns a series of strings! Bad news: It's 4x slower.

Python Logic: Is this Math or Magic?🤔 Day 8 of my Python journey! C++ logic tells me: You can't add words to numbers. Python logic says: Hold my coffee ☕ Check out this snippet: result = True + True + False * True What do you think the print(result) output will be? Drop your guess in the comments! 👇 A) True B) 2 C) 3 D) Error Hint💡: It comes down to how Python stores Booleans as Integers! #Python #LearninginPublic #30DaysOfCode #ProgrammingLogic #Day8

I built a Python CLI toolkit because everything felt fragmented Created by Arjun M Most Python CLI tools start simple… and then slowly turn into chaos. You begin with a couple of commands, maybe argparse, maybe click. Then you add prompts. Then state. Then formatted output. Then some sort of flow. And suddenly your “small CLI tool” looks like a badly stitched Frankenstein of ut... link https://lnkd.in/eXHSCBSX pubDate Sat, 11 Apr 2026 03:28:37 +0000

Python Challenge – Can you solve this? Today was all about deep-diving into Lists vs. Sets and I came across a common mistake that we can sometimes overlook. Let’s test your Python understanding👇 numbers = [1, 2, 3] numbers.append([4, 5]) print(len(numbers)) A) 3 B) 4 C) 5 D) Error It’s a classic interview question that tests if you truly understand how Python handles memory and lists.
