Python Tip #99 (of 365):
Don't convert pathlib.Path objects to strings
Using a pathlib.Path object in an f-string or a print call is fine and I do this often.
But if you THINK you need to convert a pathlib.Path object to a string to pass it off to some other path-handling utility, you probably don't need to. Most path-handling utilities in Python support pathlib.Path objects just fine.
Have a date string and want to find the format string needed to parse it?

I've updated my blog post on how to have a great first #PyConUS: https://trey.io/first-pycon
The only TBD links are the volunteering link and the open spaces links.
I'm considering making an audio recording of this post for folks to listen to during the travels to Long Beach. Anyone interested in that?
I'm surprised at how well that came out. I'm VERY curious about the process that was used to make this.
Something (or someone?) clearly removed the background from my avatar and there's some decent wrapping of text (which I hope holds up well for even longer titles).
I tried generating one for my talk also, but it looks like both buttons go to the same image.
Props to someone on the @pycon team for making such a fancy image!
@simoncrowe yeah that was nearly half the space on my drive.
I had been clearing old files away because my drive has been filling up recently.
I realized today that my disk usage analyzer tool showed WAY less space used than actually made sense given the size of the drive and the available space... turns out I needed to run it with root access to see the mess that docker had been making.
“While splitting on a line feed character will often work, I recommend using the string splitlines method instead.”

@glyph yup!
$ docker system prune -a
...
Total reclaimed space: 18.79GB
$ docker volume prune

Total reclaimed space: 224.4GB
Yikes...
Python Tip #98 (of 365):
Don't use open method on pathlib.Path objects 🧵
Instead of this:
with path.open() as file:
...
Prefer this:
with open(path) as file:
...
Since Python 3.6, pathlib.Path objects can be passed to the built-in open function.
pathlib.Path's open method is a relic from an earlier version of pathlib that wasn't yet fully embraced by Python's various path-handling features.
I recommend using Python's built-in open() function everywhere.
