What combination of python-mode, ipython, (ipython.el) versions/releases and init.el/.emacs.d code work?

Question

My goal is to use Emacs 24 as my python editor ( also has a Matlab and R editor but that's not what my question is about ). (Please let me know if I left out any information or if I did not state something clearly.) I've been able to set up my packages and my init.el file in such a way that I'm able to get tab completion, correct highlighting and snippets for python. I'm using python-mode.el as my python mode. The problems all revolve around this: I want to use ipython as my python shell, in order to use its tab completion functions when debugging scripts. - However, when I start ipython (using M-x ipython) I have no tab completion. Furthermore, it does not show "[1] in:", however it does show "[1] out:". - I would like to make ipython my default shell in Emacs. However, attempts at this have failed (e.g. setting C:\PATH\TO\IPython.exe onto py-python-command). - When I try to run my python script using C-c C-c it runs using the normal Python, and indeed stops at the position I tell th…

With Emacs24, I use the default python.el (not python-mode.el), which started on github.

when I start ipython with `python-shell-switch-to-shell` or `C-c C-p` (Python menu -> start interpreter), I get ipython. Tab completion works.

ipython is the default python interpreter (see my init file)

when I have started a ipython shell I can send a file or the selected region to it (commands available in the menu), and it gets evaluated correctly.

As a side note, you can start the jedi autocompletion with `jedi:setup` when you are in a python shell. It gives nice popups with parameters help and doc, and you can choose to fire it at the dot (instead of after 3 characters). See IPython auto-completion emacs24 doesn't work . It can be seen as a complement rather than a replacement to ipython.

Following my config:

```
;; trying ipython tab completion: that works :)
(setq
 python-shell-interpreter "ipython"
 python-shell-interpreter-args ""
 python-shell-prompt-regexp "In $$[0-9]+$$: "
 python-shell-prompt-output-regexp "Out$$[0-9]+$$: "
 python-shell-completion-setup-code "from IPython.core.completerlib import module_completion"
  python-shell-completion-module-string-code "';'.join(module_completion('''%s'''))\n"
  python-shell-completion-string-code "';'.join(get_ipython().Completer.all_completions('''%s'''))\n"
     )
```
