C-c # is a command of python-mode.el, that is not part of Emacs.
To uncomment you have just to C-u C-c #.

However,you are probably using the python mode that come with emacs.
So with this less mode you will have to use M-; that can lead to
problems of indentation in the lines that come after commented lines
made with M-;.

So if you work a lot on python, you should use python-mode.el.

Commenting out block of code in emacs in python mode

[alex47387]

Hi,

I hope I am posting this question in the right forum; otherwise please let
me know. 

Here is my problem:
I usually develop python code with emacs, emacs being in python code. On my
desktop a version is installed and/or configured that way, so I easily can
choose a region in the code and simply click on a menu option to comment out
this block of code (i.e. at the begin of each line in the selected code two
'##' are put). That is very convenient.
However, on my Laptop, running F12 and emacs 23.1.1, this menu option is
missing! I searched within google and found the hint that by pressing 'C-c
#' I also can comment out a selected region. But on my emacs it says: 'C-c #
is undefined'. Am I missing something? Anyone any idea how to
fix/install/update/solve this problem, so I can easily choose a couple of
python lines and comment them out?


Thanks
  Alex
