Ciao Yuan,
I found a bug in python-ts-mode, it does not handle treesit-font-lock-level 
even as a list. The attached patch fixes this bug.

Thank you.

Vincenzo

Subject: [PATCH] python-ts-mode now handles the treesit-font-lock-level
 correctly.

'treesit-font-lock-level' can be a number or a list, it should be
handled using 'treesit--compute-font-lock-level'.

* lisp/progmodes/python.el (python--treesit-fontify-string): Apply
'treesit--compute-font-lock-level' to 'treesit-font-lock-level'.
