Oh, I didn't mean it to completely replace me grading things, but I think it

useful if there were a lot of little assignments that could be done

Are there any good docs for this?

Thanks for all who replied to this question about replacing a method. I feel a
little sheepish for not having caught that I have to replace it in the class,
not the
instance, but I have found a very similar problem trying to replace a method
using a
function defined in pyrex. I post all of

Are there advantages/disadvantages? I have used enthought before, but it seems
as if
they are not at 2.4, and may lag behind in versions (which may not be a bad
thing).
Any other recommendations?
thanks,
Brian
questions will get me a
long
way. Let me know what you think! Please be gentle, because this is really my
first
somewhat significant python project, so there is probably some cruft from my
Matlab
and C experience (stray semi-colons here and there, etc.)

I'd like to ask, being new to python, in which ways is this array object far
superior
to Matlab's? (I'm not being sarcastic, I really would like to know!)

The sort method on lists does in-place sorting. Is there a way to do what I
want here?

t has
an infinite loop, I don't want to freeze at that point. If it helps, this part
of
the code is already running in a thread, so I guess I could time-out the thread
rather than the execfile. Is there an easy way to do that?
thanks,

an I get the line number in "somefile.py" where the error occurs? When I
do the
above, I get the line number in the script which calls execfile instead.

Hello,
In my attempt to learn python, migrating from matlab, I have the following
problem.
Here is what I want to do, (with the wrong syntax):
from numpy import *
t=arange(0,20,.1)
x=zeros(len(t),'f')
idx=(t>5)
tau=5
x[idx]=exp(-t[idx]/tau) # <---this line is wrong (gives a TypeError)
#
u exit the interpreter, the script continues
from
where it left off. Is this possible in python?

ng on context.
There is
a dialog class which allows you to edit/change the values, and a wrapper
function of
the form: new_params <== wrapper(old_params) which calls the dialog, and
returns
the updated params instance.

thanks for the pointer! it is a bit confusing with all of the different
numerical
modules (Numeric, numpy, scipy, ScientificPython, numarray, etc...
Numeric.arange(1,11,1)
idx=Numeric.nonzeros(a)
a=a[idx] % doesn't work
and what about meshgrid? Do I use the fromfunction() in some way? Is there a
resource that goes through comparisons like this?
