+As alluded to in [[id:e816f747-a7de-4111-af8d-63725df90a99][Poetry2Nix Development Flake with Matplotlib GTK
+Support]], I'm currently in the process of getting my "new" python
+workflow up to speed. My second problem, after dependency and
+environment management, was that fancy REPLs like [[https://ipython.org/][ipython]] or [[https://github.com/prompt-toolkit/ptpython.git][ptpython]]
+don't jazz well with the standard =comint= based inferior python repl
+that comes with =python-mode=. One can basically only run ipython with
+the =--simple-prompt= flag which removes features like
+syntax-highlighting and auto-completion. Especially annoying is, that
+only the =tkinter= backend for =matplotlib= works in this mode.
+
+The package =elpy= comes with some improvements, especially when it
+comes to sending part of a buffer to the repl, but it comes with all
+sorts of baggage that interfere with my emacs setup.
+
+From my jolly [[https://julialang.org/][Julia]] day I'm used to [[https://github.com/shg/julia-vterm.el][julia-vterm]]. This emacs package
+runs a Julia REPL using a full terminal emulator ([[https://github.com/akermu/emacs-libvterm][emacs-libvterm]]). So
+in the pursuit of a nice hack, I ~M-x replace-string~'d the word =julia=
+with =python= and gave it a shot. Remarkably, the whole thing just
+worked without much tweaking and you can enjoy the result by checking
+out the [[https://github.com/vale981/python-vterm.el][GitHub repo]].
+
+The idea of extending the original =julia-vterm= package to support
+python as well is not without elegance. However, the code base is not
+too large and -- owing to the differing sensibilities of the julia and
+python communities -- the feature-set is likely to diverge in the
+future.
