There is a longer story to that name, for that reason I think it fits, but I see your point.

Although I did years of Python in my early days I totally forgot the pyxxx naming convention. Looking at it today I think that convention only applies when py is the prefix for another word (pytorch, the torch for Python). That doesn't work with Pylon (Pylon, the lon for Python).

So basically Pylon is a read word and the other pyxxx packages aren't.

Also a great css tool for creating quick designs in html https://almonk.github.io/pylon/

There is also driver for Basler cameras with that name. It has Python bindings - with name: pypylon.
