Savannah submitted a PyCon 2026 proposal but I've cunningly edited the screenshot to read "Python 3.14 3.141592653589793238462643383279502 to 33 decimal points"

Some stats from core dev @hauntsaninja.bsky.social showing Python 3.14 had more usable packages on day 1 than other recent releases.

New releases of #cibuildwheel adding 3.14 as optional and then default also helped.

Python adoption chart showing number of packages definitely supporting 3.11 to 3.14 against time since final release, starting at -400, going to +1000 days, where available. All curves follow a similar trend, but newer ones have more available earlier. The trend is fairly flat at -400, but around -300 start picking up, and at day zero all increase a lot. Similar to the previous chart, but Python adoption amongst packages with version specific wheels. Here, the new versions have much greater adoption than earlier ones.

We released Python 3.9, 3.10, 3.11, 3.12, 3.13 and 3.14 this week but I'm sorry you're going to have to wait until next week for 3.15.

Instead of typing the name of the package to check, leave it blank and it'll check pyproject.toml/setup.cfg of the current directory.

Or point it at another directory.

Days since running coverage on tests found a bug in the tests: 0

This time, a generator had already been exhausted, before we tried to iterate over it. The lack of coverage highlighted the problem.

#Python #tests #coverage
Code: append_images = (Image.new("RGB", (1, 1), color) for color in colors) im_reloaded = roundtrip(im, save_all=True, append_images=append_images) for im_expected in append_images: im_reloaded.seek(im_reloaded.tell() + 1) assert_image_similar(im_reloaded, im_expected, 1) And then Codecov warns these last two lines weren't covered.

Here's the 15k most popular packages from hugovk.github.io/top-pypi-pac... charted. The second is with log scale.

#Python #PyPI #LongTail
A chart showing PyPI downloads for the top 15k projects. It starts at around 1.2 billion, and quickly drops down around to near zero between rank 200-1000. Similar but we can more clearly see it drops to around 100k downloads around rank 7,500.

Seems this "plug" predates Plugge
web.archive.org/web/20241226...
Dear Word Detective: I am looking for the origin of the verb "to plug," meaning to promote a book, song or movie in the media. The closest I have found to a credible suggested origin is the name of the founder of one of the earliest commercial radio stations, which operated from northern France in, I think, the 1930's, his name being Mr. Plug (Plugg?). Are you able to confirm or refute this story? -- Stuart Middlemiss, via the internet. I'll take "refute" for $200, Stuart. The verb "to plug," meaning to publicize or promote a book, movie, song, business or other creation by mentioning it in the mass media, does not come from the name of Mr. Plug, assuming he existed in the first place. Of course, eponyms, words formed from the proper names of people or places, are very common in English. "Sandwich" (popularized by John Montagu (1718-1792), the fourth Earl of Sandwich) and "Graham crackers" (after Sylvester Graham (1794-1851), a Presbyterian minister who was convinced that eating meat caused lewd behavior and that catsup caused insanity), are among the thousands of eponyms in everyday usage. But we have no need of Mr. Plug, whether he be real or imagined. "Plug" has been used as both a noun and verb in this "Hey, buy my book" sense since at least 1906, and is a logical outgrowth of the more general senses of the word. In the beginning was the Middle Dutch word "plugge," meaning a stopper of wood or other material used to close an opening. Brought into English in the 17th century, "plug" sprouted a wide range of uses from the literal (as in "electrical plug") to the metaphorical ("to plug" meaning to shoot or punch someone). One of the figurative uses of "plug" appearing in the mid-19th century was "to plug away" at something, meaning to work very diligently, also found in the use of "plug" to mean a horse worn down by hard work. It was this "hard, diligent work" meaning that later developed into the "shameless promotion" sense we use today.

norwegianblue now uses this to create narrower tables.

Before: running "eol alpine" shows a wide table in the terminal, the last column made of long links to release notes. After: running "eol alpine" shows a narrower table in the terminal, no links column, and the release names in the first column are underlined and clickable.
