Well, for me, there aren't any strong negative reasons really. I just felt that the interface was a bit 'clunky' (the extraneous use of spaces and newlines makes me nervous), the commands/shortcuts were non-intuitive to me and I just don't like reading docs before trying out something -- which I think is required for using ipython. However, i still do recommend it to people who want colors, completion and all sorts of customization abilities from their prompt. cheers, - steve -- random non tech spiel: http://lonetwin.blogspot.com/ tech randomness: http://lonehacks.blogspot.com/ what i'm stumbling into: http://lonetwin.stumbleupon.com/ ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

[..] Do you have any reasons why? It's praised a lot in some circles but I got a lot of negative comments about it on the #python channel. I personally don't use it unless I'm teaching the language since it's perceptibly slower to start up when your python installation is on NFS. -- ~noufal http://nibrahim.net.in ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

Hello:
I have been using CPython as a calculator, while I do all those number
crunching in C. SO, 'import math' is a must.
This is what I did:
- Create a file: .pythonrc in my $HOME and place this line:
There are other goodies you can put there as well. I used to have
import readline
readline.parse_and_bind("tab: complete")
in there so that the default interpreter would get tab completion.
I also have this is my .pythonrc:
import os
import readline
histfile = os.path.join(os.environ["HOME"], ".pyhist")
try:
readline.read_history_file(histfile)
except IOError:
pass
import atexit
atexit.register(readline.write_history_file, histfile)
del os, histfile
This lets you save the history of every thing you type in your interpreter
session much like the bash history functionality. This is immensely useful when
I am trying out stuff on the prompt before creating a script.
Of course all this also comes built-in with the Ipython environment, but I never
really got hooked on to that.
Anyways, besides the tip, I'd also like to point out to the 'atexit' module
which the above tip uses. It is included in the stdlib and can prove to be quite
useful at times. That one is good to know about.
cheers,
- steve

Neat !! :)
btw does Ubuntu come with readline by default??
I'm not sure what you mean by "with readline" but the readline module
is as far as I know part of the Python standard library.
I meant readline development module. anyways turns out it doesn't ...
