Collection(s) of counter-intuitive Python behaviour
This is kind of a shot in the blue: Some time ago I found a  (GitHub?) repo that collected unexpected/surprising Python behaviour. Ofc this depends on ones knowledge but it is stuff that is counter-intuitive if you don't know it or the internals.

The first example was [internal caching of -5...256](https://www.reddit.com/r/Python/comments/18leav/python_integer_range_5_256_and_identity_comparison/) and all the consequences of that (ids, is), …

If you don't know that particular repo, do you know similar behaviour? I found this [Python oddities talk](https://treyhunner.com/python-oddities/) but that wasn't it.

Secondary question: What would be a good source for this (edit: finding oddities/inconsistencies)? I enjoyed to learn what's new by reading the release notes &lt;3. I found looking/searching through [bugs.python.org](https://bugs.python.org/) quite interesting, because you can follow a discussion about aspectes of the language properties/behaviour, same idea why I skimmed PEPs and their discussion.

However, there is always something one does not know and I want to learn all of that. For that reason I am keeping a file in which I document parts of the language that I am not that used to, and then I mostly play around with `ptpython` and try stuff which I try to use later on if it seems like a good fit.

I guess well fitting flairs are discussion, help, resource, … but since I can't really decide I am choosing help. after all I want help to find a resource which could provide material for a discussion.
