* Python
#+BEGIN_SRC emacs-lisp
  ;; (leader-def-key "sp" #'elpy-shell-switch-to-shell)
  (leader-def-key "sp" #'run-python)
  (add-hook 'python-mode-hook #'disable-tab-insert)
#+END_SRC

Elpy is a python IDE package:
#+BEGIN_SRC emacs-lisp
  ;; (use-package elpy
  ;;   :init (elpy-enable)
  ;;   :config (setq elpy-rpc-python-command "python3"))
#+END_SRC

Alternatively, use the LSP python client:
#+BEGIN_SRC emacs-lisp
  (add-hook 'python-mode-hook #'lsp)
  (general-def 'normal python-mode-map "C-c C-d" #'lsp-describe-thing-at-point)
#+END_SRC

Support pyvenv within Emacs:
#+BEGIN_SRC emacs-lisp
  (use-package pyvenv
    :commands (pyvenv-mode pyvenv-workon pyvenv-activate)
    :init
    (add-hook 'after-init-hook #'pyvenv-mode))

  (defun eshell/workon (name)
    (pyvenv-workon name))

  (defun eshell/activate (dir)
    (pyvenv-activate dir))

  (defun eshell/deactivate ()
    (pyvenv-deactivate))
#+END_SRC

ISort is a Python utility to sort imports:
#+BEGIN_SRC emacs-lisp
  (use-package py-isort
    :commands (py-isort-buffer py-isort-region)
    :config
    (setq py-isort-options '("-m=3"))
    :general
    (python-mode-map "C-c C-i" #'py-isort-buffer))
#+END_SRC

Pipenv is the Python standard dependency management/virtual environment tool. pipenv.el teaches Emacs its ways:
#+BEGIN_SRC emacs-lisp
  (use-package pipenv
    :hook (python-mode . pipenv-mode)
    :commands (pipenv-mode
	       pipenv-activate
	       pipenv-run))
#+END_SRC

A function to run a pipenv-aware python repl:
#+BEGIN_SRC emacs-lisp
  (defun run-pipenv ()
    "Runs a pipenv-aware Python shell"
    (interactive)
    (pipenv-activate)
    (run-python nil nil t))
#+END_SRC

Run black on the current buffer:
#+BEGIN_SRC emacs-lisp
  (general-def 'normal python-mode-map "C-M-\\" #'format-all-buffer)
#+END_SRC

[[https://github.com/naiquevin/sphinx-doc.el][sphinx-doc.el]] automatically generates doc strings for Python functions (and updates existing ones!):
#+BEGIN_SRC emacs-lisp
  (use-package sphinx-doc
    :hook ((python-mode . sphinx-doc-mode)))
#+END_SRC

And support pyenv (NOT pyvenv) to change Python versions:
#+BEGIN_SRC emacs-lisp
  (use-package pyenv-mode
    :defer t)
#+END_SRC

** Autoflake
[[https://pypi.org/project/autoflake/][Autoflake]] is a tool that removes unused imports and variables from Python code:
#+BEGIN_SRC emacs-lisp
  (defvar autoflake-args '()
    "Arguments to pass to the autoflake command.

  See URL `https://pypi.org/project/autoflake' for options.")

  (defun autoflake (arg)
    (interactive "P")
    (let ((autoflake-cmd (or (executable-find "autoflake")
			     (error "Autoflake executable not found")))
	  (file (cond
		 ((or arg (not buffer-file-name))
		  (read-file-name "Run autoflake on file: "))
		 (buffer-file-name buffer-file-name)
		 (:else (error "Invalid file for autoflake")))))
      (apply #'call-process autoflake-cmd nil nil nil
	     (append autoflake-args (list "--in-place" file)))))
#+END_SRC

** Testing
[[https://github.com/wbolster/emacs-python-pytest][python-pytest.el]] integrates Pytest with Emacs:
#+BEGIN_SRC emacs-lisp
  (use-package  python-pytest
    :commands (python-pytest-popup
               python-pytest--current-defun)
    :general
    (python-mode-map "C-c t p" #'python-pytest-popup))
#+END_SRC

And borrowing some functions from python-pytest, we can get some nosetests support as well:
