Episode #259: Design Patterns That Don't Translate to Python – The Real Python Podcast Do the design patterns learned in other programming languages translate to coding in Python? Christopher Trudeau is back on the show this week, bringing another batch of PyCoder's Weekly articles and…

On this week's episode, @digiglean.bsky.social and I talk about lots of releases, using coverage to make sure your tests are running, t-strings, and much more.

With content from: @willmcgugan.bsky.social @simonwillison.net @hugovk.dev @martinfowler.com @mitsuhiko.at and others.

Diagram showing that the keyword `elif` and an `else` followed by an `if` are treated the same at the level of the AST in Python.

The Python keyword `elif` is a lie!

But they don't want you to know that!

You are welcome.

What the Python?!

At PyCon Portugal 🇵🇹 I gave a lightning talk (5-min talk) where I showed a bunch of seemingly random Python behaviours.

Maybe 6 or 7.

Watch the talk and let me know how many of these you already knew 👇

Just found out about `pp` and `pformat`.

Glad I could help :D

Thanks for letting me know!

Printing the dictionary with keys sorted sounds kinda nice for readability 🤷

No?

Does anyone here ever use `pprint.pprint`?

I always forget this exists...

Enjoy!

clicking a number in the grid could highlight all other instances of the same number.

That'd make it easier to scan the grid :D

These are just random thoughts, though.

This is fun, thanks for the game!

It took me a while to realise that “0” is a valid number in this sudoku version 🤦

Would be cool if the numbers in the clickable input region got grayed out as you complete them.

Also, since the grid is huge and it takes ages to scan,

Nice :D I don't use fish, though 🤪

Use

`pbcopy < file.txt`

To copy the contents of the file.txt to your clipboard.

(MacOS-only, I believe.)

Congratulations & good luck! Thankfully, you still have some time to prepare :D

(Side quest: come up with 3.16 stickers that are nicer than @hugovk.dev's 3.14 stickers!)

We're announcing this “officially” at the @pyconpt.bsky.social lightning talks today!

If you'd like to stay in touch to join our monthly meetings, here's a Discord link 👇

An image generated by AI that contains the title “Python Lisbon Meetup” written at the top. The image is in shades of blue and yellow, alluding to the Python logo. The blue and yellow elements are references to the city of Lisbon, Portugal.

Who can guess what's coming? 🤔

PyCon Portugal 🇵🇹 is starting!

(A bit late, but it's starting nonetheless!)

Wish me luck – hopefully no one else cancels their talk last-minute!

P.S. I need an idea for a lightning talk... What do you suggest?

Table that shows all combinations of using \b and \B around a word pattern, showing how to match standalone words, infixes, suffixes, and prefixes, with regular expressions.

Here's a table with the base word “legal” and all combinations of \b & \B around the word.

Now, you do 😉

This was the tip I sent yesterday to my Python drops 🐍💧 newsletter.

Most folks also didn't know about it.

Just scheduled the 100th Python drop! 🐍💧

Over the past ~20 weeks I've sent 100 short, actionable Python tips to folks who want to keep improving their Python skills.

By the way, by default, \b and \B consider “word characters” to be alphanumeric characters and the underscore.

So \b and \B work really well with punctuation, too.

Pretty neat :D

Yesterday I learned that you can use \B in regular expressions to match _inside_ words.

So, combining \b and \B you can match prefixes or suffixes.

For example:

\bwater\B – matches “water” as a prefix

I like watermelon ✅
Drink water every day ❌
Is "tidewater" a real word? ❌

Does anyone use anything similar to “Markdown Here” markdown-here.com that lets you write your emails with Markdown and then uses the markdown syntax to format your email appropriately?

I had never heard about this but “Markdown Here” doesn't work for Safari 😬

Sem problema! A oferta é útil à mesma.

I meant Friday 😂

Thank you for stepping up, Luciano!

Don’t take me wrong but I’ll try to find someone to present in person.
I’ll reach out to you in ~48 hours if I fail or sooner if I succeed!

Looking down on many tables of sprinters.

Sprinters at their laptops.

Sprinters at their laptops.

An array of snacks and sweets including one with a written warning poster: "VERY SPICY. EAT ONE A TIME. CAROLINA RIPPERS. WASH FINGERS." Plus two types of Finnish salmiakki which should have a warning, and a big rainbow unicorn balloon.

Thanks to everyone for taking part in the #CPython sprint at #EuroPython2025!

Across all CPython repos this weekend:

* 122 PRs created (69 the previous weekend)
* 79 PRs merged (65)
* countless invaluable in-person discussions (a few?)

#EuroPython #Python #sprint #Prague

You really can't please everyone.

I'm going through the feedback for my EuroPython talk:

Many comments like:
“Awesome pacing, great examples”
“Well paced”
“Clear examples”
...

One comment:
“Talk was too slow and I would have liked better examples”

🤪🤡

Who's up for showing up at @pyconpt.bsky.social this Thursday to give a 30 minute talk?

We just had a last-minute cancellation!

I am REALLY excited about the full documentary that's coming out this Summer.
