matplotlib basic question

[orangeDinosaur]

Hi,

I am exploring the possibility of using python as a replacement of
MATLAB when I leave school. So, I've been playing with matplotlib and
have run into some weird behavior after recently installing python
2.5.1 and matplotlib 0.90 on my Windows XP machine. Here's an example
of what I see:

>>>from matplotlib.pyla b import *
x=arange(-2*pi,2*pi,pi/24)
y=sin(x)
plot(x,y)

[<matplotlib.lin es.Line2D instance at 0x017C38C8>]

>>show()

So, first off, what's up with the [<matplotlib.lin es.Line2D instance
at 0x017C38C8>] line that shows up after my plot command? And second,
when I call show(), a new figure pops up with my sin wave -- seems all
right, yes? But I'm not given another >>prompt in IDLE until or
unless I close the figure that popped up with the show() call.

So, after closing the figure I type this:

>>>show()
plot(x,y)

and this time another figure pops up with my sine wave again and I get
a prompt as well. But now, the figure window is completely
unresponsive -- I can't even close it without getting the "your
program is not repsonding" business. What am I missing? This
behavior so far seems pretty unintuitive.

Any clarification is appreciated!

A side question: Is there any plans of updating the scipy.org
Superpack bundle
for Mac OS X to work with 2.5?

You would have to ask Chris Fonnesbeck. It's not an "official"
binary inasmuch
as scipy has official binaries.

Okidoki. This is the last reason for me not upgrading to 2.5 as I
have a hard
time compiling things from scratch :)

Cheers

Yes, the Python Enthought Edition was being discussed and it is
currently based on Python 2.4.3.

I'm quite familiar with Python Enthought Edition as I work at Enthought. I was
confused because Colin referenced scipy specifically rather than simply saying
that the current version of Python Enthought Edition was not based on 2.5.
