Dear maintainers,

I do a lot of programming in python and have noticed that if there is a
method of a class defined with the same name as a builtin function. It
gets highlighted with the face for builtin functions and it looks
different for all the other functions and confuses me sometimes and just
looks inconsistent.

I have made a simple fix to the treesitter query and it seems to have
fixed the problem.

Please share you thoughts on this fix. This is my first time
contributing to an open-source project and to emacs. Very excited to
hear from you guys!!!

 attributes.

* etc/NEWS: Announce the effect of the changes for the treesitter-font-lock-settings for built-in functions and attributes
* lisp/progmodes/python.el (python--treesit-settings): Change the treesitter query to fetch the correct type of node for built-in functions and attributes and highlight them with corresponding font-lock face.

+*** Treesitter syntax highlighting for built-in functions fixed
+The fix highlights only the correct built-in function calls and
+attributes with font-lock-builtin-face. When some class defines
+a function with the same name as a built-in function, earlier it was
+being highlighted with the same font-lock-builtin-face, which was
+incorrect. Now, normal user defined functions will be highlighted
+with font-lock-function-call-face face and built-in functions and
+attributes will be highlighted with font-lock-builtin-face.

 ** Scheme mode
 Scheme mode now handles regular expression literal '#/regexp/' that is
 available in some Scheme implementations.
