bug#31409: 25.3; Python.el: getting function signature with eldoc is not automatic |

In python-mode, to get a Python function signature in minibuffer, an
user need to:
- Start the Python shell (M-x run-python)
- Enable eldoc (M-x eldoc-mode)
- Send function definition or import to the shell (C-M-x or M-x
python-shell-send-defun)
It's too much steps and less efficient than what we have for Emacs
Lisp. :(
It would be so nice if this can be automaticaly done. Just move the
point on a symbole and Emacs show you its signature directly.
PS: I would be okay to work on this.
