FINALLY had technical issues while delivering a remote talk.
Today I got all of it!
First, my computer froze and I couldn't even share my screen.
Then, at some point my internet connection went POOF and I dropped off the call... 🤦
Hopefully now I'm good again for a dozen more talks.

Introducing the PSF Community Partner Program! The PSF is very excited to announce this new in-kind offering that expands how we support Python community events and initiatives around the world, now and alongside future community support programs 💝🐍
Introducing the PSF Community Partner Program
The Python Software Foundation (PSF) is excited to announce the introduction of the PSF Community Partner Program. This new program is designed as an “in-kind” way for us to support Python events and initiatives with non-financial assistance through the use of the PSF logo and name, as well as promotional support via sharing qualified posts on PSF official social media accounts. The PSF looks forward to supporting Python community events and initiatives through this new program!The introduction of the PSF Community Partner Program grew out of our desire to find alternative ways to support the community during the pause of our Grants Program (read more about the resulting process below). Even so, we intend to continue offering this in-kind support program after the Grants Program reopens. Our big picture hope is that, over the long term, some community events and initiatives will continue to partner with the PSF while being financially dependent on sponsors and individual donors alone. The PSF is also working on the future of our Grants Program, including when and how we can reopen it in a way that ensures the program’s long-term sustainability while balancing the needs of the Python community. In light of the truly staggering outpouring of support from our community during the 2025 year-end fundraiser, we are now in a stronger position to reopen the Grants Program and are eager to give back in a thoughtful and sustainable way. More updates to come!As with the rollout of any new program, we anticipate small adjustments will need to be made for processes to flow smoothly and to ensure the program serves the Python community well. The PSF welcomes your comments, feedback, and suggestions regarding the new Community Partner Program on the corresponding Discuss thread. We also invite you to join our upcoming PSF Board or Grants Program Office Hour sessions to talk with the PSF Board and Staff synchronously. If you wish to send your feedback privately, please email grants@python.org.

Well, that would give you the correct answer 😬
But it's more fun to see if you can name them :D

Here's a list of the #Python keywords
It's nice that the number is so small that you can actually probably remember all of them fairly easily.

I've written this Python function so many times I should no longer be confused by it...
But I never know if it's
def clamp(v):
return min(max(v, low), high)
or
def clamp(v):
return min(max(v, high), low)
Always need to stop and think about it for a minute.

If they had used the built-in `range` this wouldn’t happen.

It's pretty cool how much you can get done in Python with so little code if you leverage the standard library.

Also, just remembered about a bunch of mammals...

One of my students today made this mistake.
If you have a project and want to test it, your tests will import your project.
So, you need to install pytest as a dependency INSIDE your project.
If you install it globally, when you run it, it can't see your own project.

Parse JSON from a string with a single function call.
Don't use this if you have JSON in a file. Use `load` for that.
This is for when the data comes in a payload, for example.
