Heads up I am running another Snipster #Python training cohort next week - we'll build this cool app:

Pybites Platform | Master Python Through Hands-On Coding Overwhelmed by tutorials? Stop consuming books and courses! Confidence will come through a lot of deliberate practice. Our platform helps you master Python and grasp Pythonic best practices.

I've completed "User input" on @pybites.bsky.social 🐍🎉 - pybitesplatform.com/bites/user-i...

Tutorials are clean — but real code is messy. 💡

Our coaching cohort helps you thrive in the wild 💪
• write tests, refactor with confidence
• debug real issues
• build an efficient dev toolkit
• collaborate using Git/GitHub
• ship code you’re proud of

You’ve done 100 Python 🐍 exercises. Now what? 🤔

Building a real app still feels out of reach. 😮

That’s where our cohorts come in - we guide you from confusion to confidence, project by project. 💪 🚀

Thanks for joining us 🎧 @tiangolo.com 🎉 and for all you do with @fastapi.tiangolo.com, other libs, and now FastAPI Cloud 😍

It will be so nice to deploy FastAPI apps with just: `fastapi deploy` 🚀

👨‍🏫 Want in?

The main cohort is full, but beginner spots are still open (or join the waiting list for the next intermediate one)

Check it out here 👉 pybitescoaching.com

🚀 Built a #Streamlit front-end on top of a #FastAPI backend for our next cohort (starting next week!) 🚀

Great stack for quickly prototyping a front-end, all #Python, no JS 😎

(For more serious web apps you definitely want JS and/or htmlx though 💡)

Learn more advanced and real world #python #developer techniques - join us for our first 6 week intermediate cohort 12th of May 🎉 🐍 💪

You pick up dozens of these small and subtle #python 🐍 tricks + idioms when you make it a habit to code on our platform every day 💡 🔥 -> join here: pybitesplatform.com 📈

𝟱 𝗰𝗼𝗼𝗹 𝘄𝗮𝘆𝘀 to use the underscore in #Python 🐍💡

• Ignore 𝘃𝗮𝗹𝘂𝗲𝘀 when unpacking

• Loop 𝗽𝗹𝗮𝗰𝗲𝗵𝗼𝗹𝗱𝗲𝗿

• Access 𝗹𝗮𝘀𝘁 𝗿𝗲𝘀𝘂𝗹𝘁 in REPL

• Format 𝗹𝗮𝗿𝗴𝗲 𝗻𝘂𝗺𝗯𝗲𝗿𝘀

• Define "𝗽𝗿𝗶𝘃𝗮𝘁𝗲" methods (convention)

See below 👇

Potentially underused #Python 🐍 feature: 𝘀𝗲𝘁 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀 💡

Here's an example how we can remove or update tags, casting new + old into sets, then performing 𝘴𝘦𝘵 𝘰𝘱𝘦𝘳𝘢𝘵𝘪𝘰𝘯𝘴 🔥

Have you used them, how? 😍

(Still on the fence about 𝘸𝘢𝘭𝘳𝘶𝘴, but couldn't bear doing 𝘴𝘵𝘳𝘪𝘱() twice 😅)

import os from pathlib import Path from tempfile import TemporaryDirectory import pytest def count_dirs_and_files(directory_path: str = '.' ) -> tuple[int, int]: """Function for counting dirs and files in a directory.""" dirs, files = 0, 0 for _, directories, filenames in os.walk(directory_path): dirs += len(directories) files += len(filenames) return dirs, files def test_only_files(): with TemporaryDirectory(dir="/tmp") as dirname: for i in range(1, 6): (Path(dirname) / f'{i}.txt').write_text('hello') assert count_dirs_and_files(dirname) == (0, 5) # refactored using pytest's tmp_path fixture + parametrize @pytest.mark.parametrize("num_files", [1, 5, 10]) def test_only_files_param(tmp_path, num_files): for i in range(1, num_files + 1): (tmp_path / f'{i}.txt').write_text('hello') assert count_dirs_and_files(tmp_path) == (0, num_files)

Making a temporary file/dur is very useful for 𝘁𝗲𝘀𝘁𝗶𝗻𝗴.

In the example below, we first use 𝘛𝘦𝘮𝘱𝘰𝘳𝘢𝘳𝘺𝘋𝘪𝘳𝘦𝘤𝘵𝘰𝘳𝘺 to create 5 temp files.

This is a great example of using a 𝗰𝗼𝗻𝘁𝗲𝘅𝘁 𝗺𝗮𝗻𝗮𝗴𝗲𝗿 — a clean way to automatically clean up resources.

pytest makes it even easier using the 𝘵𝘮𝘱_𝘱𝘢𝘵𝘩 fixture:

Do you know all these 5 powerful uses of * in #Python?

– Keyword-only args
– Extended unpacking
– Flexible funcs with *args
– Unpack into func calls
– Merge iterables

👇 See examples below — which ones do you use the most, and which ones are new to you?

A common #Polars saying:

"𝙄 𝙘𝙖𝙢𝙚 𝙛𝙤𝙧 𝙩𝙝𝙚 𝙨𝙥𝙚𝙚𝙙, 𝙗𝙪𝙩 𝙨𝙩𝙖𝙮𝙚𝙙 𝙛𝙤𝙧 𝙩𝙝𝙚 𝙨𝙮𝙣𝙩𝙖𝙭" 😍

I see why now — it's 𝗯𝗲𝗮𝘂𝘁𝗶𝗳𝘂𝗹 and 𝗳𝗮𝘀𝘁. 📈

Switched from Pandas?
What’s been your biggest win (or pain)? 🤔

#Python #Rust #DataAnalytics

🎉 💪 🔥

from itertools import combinations from difflib import SequenceMatcher tags = ['python', 'pythonista', 'developer', 'development', 'dev', 'devs'] def similar(a: str, b: str) -> float: return SequenceMatcher(None, a, b).ratio() THRESHOLD = 0.8 # tune based on how strict you want to be for a, b in combinations(tags, 2): score = similar(a, b) if score >= THRESHOLD: print(f"{a} ≈ {b} → {score:.2f}") # output: # developer ≈ development → 0.80 # dev ≈ devs → 0.86

De-duped our books category page by reconciling similar titles, e.g.

think & grow rich → think and grow rich
everything is f*cked → everything is # @%!ed

Just stdlib -> `difflib`, no external deps 🚀

(Fun fact: Django’s manage.py uses this too btw 😎)

#python #tips

from dataclasses import dataclass @dataclass class Bite: number: int title: str description: str def __post_init__(self): self.number = int(self.number) self.title = self.title.strip().title() self.description = self.description.strip() if not 5 < len(self.title) < 20: raise ValueError("Title must be between 5 and 20 characters long") if self.number <= 0: raise ValueError("Number must be a positive integer") bite = Bite(1, " example title ", "This is a description.") # Bite(number=1, title='Example Title', description='This is a description.') bite = Bite(2, "this title is waaaaaaaaaaaay too long", "This is a description.") # ValueError: Title must be between 5 and 20 characters long bite = Bite(-1, "another title", "blabla") # ValueError: Number must be a positive integer

Pydantic is awesome for data cleaning + validation, but if you want something quick + stdlib only, you can also use dataclasses + `__post_init__` 🐍 😍 - see example below. 🚀

Feel like my Python is getting rusty with AI finishing all my… sentences.
Doing some code challenges on @pybites.bsky.social with no code completions as nature intended 🪴

Who has experienced this?

#AI tools: quick wins, but more + longer debugging?

"The only way to learn a new programming language is by writing programs in it." – Dennis Ritchie

No CS degree. Went from Excel macros to #Python 🚀

Code wasn’t that clean at first, but by building a real-world solution I launched my dev career 💡

Build first, polish later! 📈

import sys, time start = time.time() list_comp = [x for x in range(100_000_000)] print(f"List: {sys.getsizeof(list_comp):,} bytes, {time.time() - start:.4f}s") start = time.time() gen_exp = (x for x in range(100_000_000)) print(f"Generator: {sys.getsizeof(gen_exp):,} bytes, {time.time() - start:.4f}s")

List vs Generator in Python 🐍💡

List: 835MB, 0.99s
Generator: 192B, 0.00s 😲

• Use `sys.getsizeof()` to check memory.
• Use generators when you don’t need all values at once.

Small change, big difference! 📈

@Pybites Books v2 is live! 🚀

Simple, fast book tracking that incentivizes you to keep #reading 😎

Gamified, clean design (Tailwind + Htmx 🙏), and loved by users already. 😍

Let’s keep #books alive 💡, especially in this day and age. 📈

Try it → pybitesbooks.com 📚

# js console.log(1 + "2"); // Outputs "12" 🤯 # py 1 + "2" # TypeError str(1) + "2" # "12"

"In the face of ambiguity, refuse the temptation to guess." 💡

Python prefers clarity over assumptions:
• No implicit type coercion
• One null: None
• Mandatory indentation = no dangling if
• Type hints + mypy = catch bugs early

>>> import this 🐍

#Python #DevTips #Coding

Elegant API design in #Python libs 🐍

• requests/httpx: no auto errors, you call raise_for_status() → full control

• newspaper3k: download(), parse(), nlp() → as needed

• pathlib.Path: / operator + chaining methods → clean, OOP fs access

Great libs don’t box you in 💡🚀

Subclassing dict or list in Python? Beware! 😱 Some built-in methods bypass your overrides.

✅ Use collections.UserDict & UserList instead! They ensure all operations respect your methods.

🚀 Cleaner, predictable behavior.
