Brian #1: (draft) PEP 679 -- Allow parentheses in assert statements
- Pablo Galindo Salgado
- This is in draft, not approved, and not scheduled for any release
- But it seems like a really good idea to me.
assert(1 == 2, "seems like it should fail")will always pass currently
- since the tuple
(False,"seems like it should fail")is a non-empty tuple.
Current Python will emit a warning
>>> assert(1 == 2, "seems like it should fail") [stdin]:1: SyntaxWarning: assertion is always true, perhaps remove parentheses?
But really, why not just change the language to allow
assertwith or without parens.
Also would allow multi-line assert statements more easily:
assert ( very very long expression, "very very long " "message", )
I hope this is a slam dunk and gets in ASAP.
Michael #2: Everything I googled as a dev
- by Sophie Koonin
- In an attempt to dispel the idea that if you have to google stuff you’re not a proper engineer, this is a list of nearly everything I googled in a week at work
- Rather than my posting a huge list, check out the day logs on her post
- Worth calling out a few:
Expecting a parsed GraphQL document. Perhaps you need to wrap the query string in a "gql" tag?- said React upgrade then started causing some super fun errors.
semantic HTML contact details- wanted to check if the
[HTML_REMOVED]tag was relevant here
editing host file- desperate times (and it didn’t even work)
Madison #3: PyCascades 2022!
- Another year of excellent and diverse talks across an array of subjects.
- Talks from some well known folks (Thursday Bram, Jay Miller) as well as first time speakers (Joseph Riddle, Isaac Na)
- PSF’s DE&I Panel is doing a meet & greet, and they have a survey they’d like Python community members to fill out.
- Socials Friday & Saturday night, sprints on Sunday.
- Tickets are still available!
Brian #4: Strict Python function parameters
- Seth Michael Larson
- We have keyword only parameters
def process_data(data, *, encoding="ascii"): ...
- notice the
encodinghas to be a keyword argument, cannot be positional.
- We have position only parameters:
def process_data(data, /, encoding="ascii"): ...
- notice the
datahas to be positional, cannot be passed in as a keyword argument
- Combine the two:
def process_data(data, /, *, encoding="ascii"): ...
datahas to be positional, and
encodinghas to be a keyword, if present.
- This way a function really can only be called as intended and all uses of the function will be consistent. This is a good thing.
- There are many benefits, including empowering library authors to make changes without weird behaviors cropping up in user code.
- extra syntax may be confusing for some new users.
- For a lot of library API entry points, I think this makes a lot of sense.
Michael #5: mureq - vendored requests
mureqis a single-file, zero-dependency alternative to python-requests
- Intended to be vendored in-tree by Linux systems software and other lightweight applications.
- Doesn’t support connection pooling (but neither does
- Uses much less memory
- Avoids supply chain attack vulnerabilities
- Consider my prod branch until PRs #2 and #3 are merged.
Madison #6: Openverse
- No, not Metaverse!
- Previously “CC Search”
- Search engine for openly licensed media, for free and public use/remix of content.
- Currently images & audio, hope to include video, text, 3D models down the line.
- Start your search here
- We now have playable times in the transcript section (example).
- Very cool tool for building regex-es I used for the above: regex101.com
- Next video is out: Do you even need loops in Python? A Python short by Michael Kennedy
- Remember, we have full-text search
- pip-secure-install - from Brett Cannon
- Python Testing with pytest is, when I last checked, the #2 bestseller at Pragmatic
- so cool
- My Maui trip was also a work trip. Gave me time to completely re-read the book, make notes, and make last minute changes. Changes went in this week and tonight is my “pencils down” date. This is getting real, folks.
- Thanks to everyone for buying beta copies and supporting the re-write.

- Shoutout to just (mentioned in Ep 242)
