Why does the python interpreter not print input code and output in emacs python shell buffer for python-mode?

Question

My current python setup in emacs is:

(setq py-shell-name "ipython") ;; sudo pip install ipython
(setq py-shell-name "/usr/local/bin/ipython")
(setq py-force-py-shell-name-p t)
(add-to-list 'load-path "~/.emacs.d/python-mode.el-6.1.0/") 
(setq py-install-directory "~/.emacs.d/python-mode.el-6.1.0/")
(require 'python-mode)
(add-to-list 'auto-mode-alist '("\\.py\\'" . python-mode))
(add-to-list 'interpreter-mode-alist '("python" . python-mode))

In a python file, I start the python interpreter with "Cc !" (py-shell). I evaluate region of codes with "Cc |" (py-execute-region).

If I execute each of the following line individually,

x = "hello world"
x
print(x)

I get the following in the python shell buffer:

In [5]: 
In [6]: hello world

If I use the default python interpreter, I get

Python 2.7.2 (default, Jun 20 2012, 16:23:33)

>>> >>> >>> hello world
>>> 

Questions:

1. Are these behaviour correct (not showing which code is being evaluated, and not showing what a python interpreter would normally print)?

2. How do I set it so that the python shell prints output like a normal python interpreter in the terminal? (with input code and output printed)

I guess I'm used to ESS for R. Thanks.

Your are looking for feature, which might be implemented.

In cases like this, please file this as question at

When done, use at bottom "(+) Create bug report".

It creates a ticket, which helps us to track the issue.

Alternatively you may create a Blueprint and link a ticket afterwards.

Done so far:

Beside, your init displays some useless code - however not harmful. Second setting of "py-shell-name" takes the symbol of the first one.

"...-mode-alist" stuff is already done from python-mode, you must not care for.
