Multi-Line Comment

[Doug Tolton]

I've been using Python for quite some time now, and I'm a bit stumped.

Does it really not have a multi-line comment? I think I must just be
missing something simple and stupid.

Thanks in advance.

Nope, no multi-line comment. The python-mode package which is available for
Emacs and XEmacs supports commenting a block of text. You can also use
triple-quoted strings:

How do you comment the block of text with Emacs? That is what I'm
using for my code editor.

I was wondering if a triple-quoted string not assigned would work, but
I hadn't got arround to trying it yet.

using for my code editor.

In Python mode, use C-c # to comment the selected region and C-u C-c #
to uncomment a region. The commenting is done with "##" at the front
of every line in the region, so it normally stands out from actual
comments due to the #-doubling.

C-c #

I use C-x r k to uncomment (kill-rectangle), but I'm sure there must
be an uncomment-region in there somewhere...

The only trouble with TCSs is that emacs gets confused more easily
than with '## ' multiline-comments. And recent CVS python-modes have
had broken docstring fill (still broken, actually, whitespace gets
collapsed sometimes... must file a bug).

Just do C-u C-c #

That always stumped me as well. Any idea what the justification for this
was, Skip?

none of the other shell/script languages have one either. I rarely miss it.

(along with block indent/dedent with a decent editor)

In emacs what are the key strocks for block indent and dedent?

Man, I wonder if I'll even learn 10% of the Emacs keystrokes.

I don't even know 1%, but I know the 1% that counts.

From inside an Emacs python buffer, do

M-x py-describe-mode

Man, I wonder if I'll even learn 10% of the Emacs keystrokes.

And then, you'll realise than pre-made keystrokes are only a small part
of all available commands. And then, you'll realise that all available
commands are only a small part of all available functions. And, of course,
all of the above is only a small drop in the ocean of possibilities given
by the capability of extending the editor with new functions. At times,
I wonder if this should be seen as comforting or frightening.

Oh cool. I've been using C-x r o and C-x r k to open and kill
rectangles. Your way seems much easier. Thanks.

-tom!
