I follow @PyPi on Twitter, which just streams Python package announcements. It’s a cheap way to get exposure to new and interesting modules. But everyday it seems like there a couple of newly minted 0.1 packages for “printing nested lists”. Curious but not worth investigating.
They’re generated by people following along an example in the book Head First Python.
The book’s author has amended the lesson (through errata and next edition I guess) to point learners at testpypi.python.org (which didn’t exist at the time the book was written).
I run a cleanup script that deletes them every now and then. I haven’t run it for a while… I’ll put it on my looong TODO list…
