If there are other (fully functional) chess engines written in Python, I'm waiting for them at my tournament. There are many attempts on GitHub....unfortunately just attempts....
To establish the exact location in the hierarchy of the eleventh engine (written in Python) on which I have (thanks, again, Maestro Jim) I organized a small tour. Unfortunately, the engine is far from the 2000 CElo claimed by the author. However....the engine (Obsidian_Python-comes from Morocco) plays chess....

My OBSIDIAN_Python TEST after 52 games:

Image

It is clear to me that the engine falls into the same category as Feeks and Valiant. Maximum 900 CElo points. Far from the 2000 claimed by the author (Imran AKKI-Morocco).

It just so happens that Valiant Mk8_x64 is the only chess engine written in Python (out of the eleven I have) tested by CCRL:

Sometimes OBSIDIAN_Python has nice moves (and games). You have an example below:
