Really enjoyed my chat with Kishan Patel on our @pybites podcast.

We decided to do something different for #BlackFriday Instead of selling you "content," we're discounting "accountability." For the first time, we've slashed the price on our #Python Snipster (Intermediate) and Foundations (Beginner) cohorts (30-35% off).

Did you know you can search our #Python content from the command line? It's one of our open source libraries called `pybites-search` Easy to run (alias) using uvx:

Tired of tutorials that don’t go anywhere? 👉 Start implementing these kind of patterns in our 6-week Snipster program: pybitescoaching.com

One of my favorite design patterns: the Repository Pattern. 😍 It keeps business logic separate from the data layer. 📈 Need to swap SQL for CSV or add an API backend later? Plug it in, the interface stays the same. Example below 👇

I solved a Bite today and used collections.Counter() 🙂 Good reminder: the right data structure saves a lot of code. 🐍 In this case: apart from a small helper function, you get the top stock by symbol using most_common() Clean, fast, readable. 🚀

One of our PDI clients is building a time tracker app with SQLModel + Flask. It started simple, then grew as he hit real-world edge cases. That’s where the real dev learning happens: ⏱️ Format times ⛔ Avoid duplicates 🛠️ Handle errors clearly What are you building this week?

Perhaps there is yet hope. futurism.com/artificial-i...

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

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 👉 pybitescoaching.com #Python #Developer

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` 🚀 www.youtube.com/watch?v=Q_8a...

I've completed "Build unix' wc program in python" on @pybites.bsky.social 🐍🎉 - pybitesplatform.com/bites/build-...

I've completed "Pybites date generator" on @pybites.bsky.social 🐍🎉 - pybitesplatform.com/bites/pybite... #python

👨‍🏫 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 😅)

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? #coding #tips

Keep up2date with relevant #Python developer tips + industry trends joining our weekly @pybites.bsky.social Newsletter: pybit.es/newsletter 💡 🚀

Becoming a proficient #Python dev isn’t just about syntax, it’s about building usable apps with clean, testable, well-structured code. That’s what we coach in our 6-week cohort starting next month. Real apps. Real feedback. Real growth. 💪 More info: pybitescoaching.com

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

🎉 💪 🔥

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

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. 🚀 #python #tips

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? (image source: www.reddit.com/r/Programmer...)

"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! 📈

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! 📈 #Python #tips #performance

@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 📚

"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. #Python #tips

💡 You can use a class method to add an alternative constructor to your class. Inspired by `datetime`, the `MyDate` class below lets you create instances from a `date` or a "YYYY-MM-DD" string. 🚀 #Python #tips

Need to grab just the first and last items from a list in #Python? 🐍 You could use slicing: first = words[0] last = words[-1] Or take advantage of tuple unpacking with a throwaway variable 🚀 first, *_, last = words Which way do you prefer?

Yesterday I praised the built-ins, but the same goes for #Python's Standard Lib 🐍 😍 In the example below I reduce 7 lines of code to one elegant one-liner, making use of the fact that there is a container type available for counting an iterable (or mapping). 💡 Shorter, cleaner, more optimized 🚀

Keep it simple, keep it Pythonic 🐍 "Simple is better than complex." – Zen of Python Python’s built-ins = cleaner, more readable code! 💡 Check if all numbers in a list are divisible in one clean line. 😎 Don’t leave the house without them! 🚀 #Python #Tips #CleanCode

When to use comments? Explaining what the code does? ❌ Explaining a non-obvious design decision? ✅ 👇 Example below: 💡 Good comments save devs: ✅ Processing time ✅ From breaking subtle logic by "cleaning up" code Comment or not to comment—what’s your take? 🤔👇

Want to build your own code quality tools? 🔍 Python’s `ast` module lets you analyze code like linters do! 💪 Below code snippet extracts all function & method names from a file. What would you automate? 💡 #Python #AST #CodeQuality

🐍 Python vs. Rust: Iteration Compared 🦀 Python's zip() makes pairing iterables simple. Rust does the same with method chaining on iterators—a different but powerful approach. Check out the difference 👇

What is this `if __name__ == "__main__":` at the end of a #Python script? 🐍 It's typically used to include code that 💡 • ONLY should run if the module / script is called directly, • and NOT upon importing it. Quick example to see this in action ->

Found this cool #Python decorator trick! 🐍🚀 Instead of manually adding | (pipe) support to classes, use a decorator + metaclass to centralize it (= more DRY!): @add_llm(llm) class Recipe(BaseModel): ... Similar to pathlib.Path / "file"—elegant operator overloading! 😍 Full code 👇

🐍 #Python Tip: Save memory with `__slots__` 🚀 Instead of a dynamic `__dict__`, it defines a static structure, preventing new attributes but saving significant memory. 💡 w1.a = 1 ✅ w2.a = 1 ❌ (AttributeError) 📌 Check the image for full code & memory comparison below. Have you used __slots__? 💡👇

🚀 Just started exploring Django Ninja—FastAPI-style routing inside Django! Built my first endpoint for a books app, and it’s fast & intuitive. Django devs, this is worth checking out! Anyone else using it? 👇 #Django #FastAPI #Python #DjangoNinja

How to add a console script to your #Python package with uv 🚀 1️⃣ Init a package: uv init --lib mypackage 2️⃣ Add function to module 3️⃣ Define [project.scripts] in pyproject.toml 4️⃣ Build: uv build 5️⃣ Install + run: uv pip install -e . && uv run hello Detailed steps 👇

#Python’s Standard Lib keeps blowing my mind. 🐍 Need a month calendar? Use `calendar.monthcalendar()` - a simple matrix with sensible defaults, very clean! 🚀 Or use `calendar.Calendar()` + `.itermonthdates()` to iterate over all month dates (lazily loaded with a generator 😍)
