Hello,
I want to implement some lisp functions for the following:
1. Insert comment - when mark some lines of code and using it, insert
ins-comments, like this:
before:
l = []
l.append(1)
then mark it and use ins-func, after:
# ins > <username>, <current date and time>
l = []
l.append(1)
# ins < <username>, <current date and time>
Please, help me with some general code, thanks!

If I understand correctly, you want to implement some lisp to comment
your Python code? Have you tried Python mode? There is a commonly used
key (M-;) that comments lines and regions --- look up the function
"comment-region." In each programming language mode, this function
inserts the proper comments for the language you are using (e.g., ";"
for lisp and "#" for Python, Perl, et al).
Please be specific if you want something else.

Alex,
is this what you want?
(defun ins-comment (beg end)
(interactive "r")
(let ((str (concat user-login-name ", " (format-time-string "%d/%m/
%y %Hh%Mmin"))))
(goto-char end)
(insert "# ins < " str)
(goto-char beg)
(insert "# ins > " str "\n")))
HTH,
hugo

Python-mode provide a command for indenting that is bind to:
C-c # ==> comment
C-u C-c # ==> uncomment
The command is: `py-comment-region'
It is better to comment with that instead of the usual M-;
because it don't affect indentation after a block of commented code.
I don't know if python.el provide the same.

Do you mean that this is a bug in the support for M-; in phyton-mode? Or
is it a bug in M-;

I don't think it's a bug, it's just better to comment with the proper
function in python, especially if there is complex level of indentation
(loop followed with other loop and if if if...etc).
However M-; work in most cases.
So if it's a bug, it come from python-mode, because M-; normally have to
be used with python.el (is it working with python.el ?) because it is
the normal mode to use in emacs with python even if IMHO python-mode is
much better.

But isn't there a bug somewhere if M-; does not do the right thing?

Well, if emacs is meant to use python with python.el and it is working
fine with it, it is not a bug, but if M-; don't work properly with
python.el, yes, it is a bug!
I don't know how emacs is working actually with python.el because i
don't use it.

Don't you think that all major modes should support M-;? There are easy
ways to do that. The doc strings says
(comment-dwim arg)
Call the comment command you want (Do What I Mean).
If the region is active and `transient-mark-mode' is on, call
`comment-region' (unless it only consists of comments, in which
case it calls `uncomment-region').
Else, if the current line is empty, call `comment-insert-comment-function'
if it is defined, otherwise insert a comment and indent it.
Else if a prefix arg is specified, call `comment-kill'.
Else, call `comment-indent'.
You can configure `comment-style' to change the way regions are commented.

Yes, i think that is enabled and working (indenting a comment block).
That is not working always correctly is indenting code after a block of
comment if this comment is commented with M-;. May be it's only because
M-; comment with only one # with no space in front.
Sure it can be corrected, i never ask myself about that as i use C-c #
in python.

Thanks to everebody, I just returned from buisness trip and read your answers.
weber - almost what I wanted, thank you for example, I will modify
your example for my needs.
