I am new to python. I guess there are libraries called numpy, anaconda etc. What the best init.el setup for this. (I want to work on ML or Data Science)

    Following is my configuration for Python; I am using Emacs 29.1 --with-tree-sitter:

      (use-package treesit
    :config
    (setq treesit-language-source-alist
	  '((python . ("https://github.com/tree-sitter/tree-sitter-python.git"))))
    (add-to-list 'auto-mode-alist
		 `("\\.py[iw]?\\'\\|python[0-9.]*" . python-ts-mode)))

  (use-package eglot
    :hook ((python-mode . eglot-ensure)	; pip install 'python-language-server[all]'
	   (python-ts-mode . eglot-ensure)))

    I have something like this

    ;; ----- language server

(require 'eglot)
(add-hook 'python-mode-hook #'eglot-ensure)
(add-to-list 'eglot-server-programs
	     `(python-mode
	       . ,(eglot-alternatives '("pylsp"
					"jedi-language-server"
					("pyright-langserver" "--stdio")))))

;; ----- treesitter

(use-package treesit-auto :ensure t)
;; treesit grammar should be installed here: "~/.emacs.d/tree-sitter/"

;; ----- select interpreter

(setopt python-shell-interpreter ("~/miniconda3/bin/python"))
(setopt python-shell-interpreter-args "-i")

;; ----- conda

(use-package conda
  :ensure t
  :custom
  (conda-anaconda-home "~/miniconda3")
  (conda-env-home-directory "~/miniconda3")
  (conda-env-subdirectory "envs")
  :config
  (unless (getenv "CONDA_DEFAULT_ENV")
    (conda-env-activate "base"))))

;; ----- emacs-jupyter

(use-package jupyter
  :commands
  (jupyter-run-server-repl
   jupyter-run-repl
   jupyter-server-list-kernels))
(org-babel-jupyter-override-src-block "python") ;; so python becomes jupyter-python in org-babel

;; ----- other settings

(setopt python-indent-guess-indent-offset-verbose nil)

      I had to uninstall the conda package because it was constantly disconnecting and reconnecting to the kernel and every time it’d do that Emacs would freeze for a couple of seconds. Probably happened about 10 times a minute before I finally deleted the package.

    I use Emacs 29.1 or Emacs 30, because:

    1. they have built in LSP support by Eglot.
    2. they have built in tree-sitter support by python-ts-mode

    And I use pyright as the LSP backend.

    After install pyright, just start Emacs, open python file and M-x eglot will fire up the lsp support.

    For the python virtual environment, I use envr(direnv)on macOS and Linux, use pyvenv on Windows platform.

    You can see my personal configuration here:

    jedi-language-server + eglot only.
    maybe i’ll extend it to support running unit tests.
