That all looks cool. I will experiment more. I'm a bit slow on this as only 
two weeks old so far.

Thanks for the patience

Thank you.That is what I was looking for, but as often seems the case, one 
thing exposes another. Is there any way to listen for events without 
specifically binding to a handler (it seems one cannot bind an event to two 
handlers?)? One could do so with globals, but I'm trying to avoid that.

For example, "press any button to stop"


def HandleSomething(self, event):
.
 while generating_control: == something:
run
else
stop

A question about event handlers with wxPython

[Erik Lind]

I'd appreciate any pointer on a simple way to tell within an event handler 
where the event came from.
I want to have "while" condition in a handler to stop or change processing 
if an event occurs from some other button click.

Trying to bind more than one event to the same handler still doesn't tell me 
where the event came from in a basic bind. Is there an argument I can put in 
the bind so as to identify the source of the event in the event argument? .

help with slicing/replacing matrix sections.

[Erik Lind]

I see a more complicated thread on a similar sounding question, but my 
question is simpler, I hope.

I have a large numpy matrix, initially created as:

Mat = zeros((a,b), int)

and a smaller array with other data

Sub = [1,2,3,4,5],[6,7,8,9,0]

I want to replace a section of Mat matrix with Sub matrix without having to 
loop through each cell in each matrix individually.

I thought index/slice assignments, should be able to do that, but I can only 
get it to work (as per book examples) with simple arrays. Every syntax 
combination I have tried gives one error or another, typically "can't 
broadcast an object", but intuitively it seems there should be a simple 
solution.

In short, how do I insert the data in the two (or any number of) rows in 
Sub[0:2] into any part of Mat starting at Mat[x,y] without using "for" loops 
?

__init__ explanation please

[Erik Lind]

I'm new to Python, and OOP. I've read most of Mark Lutz's book and more 
online and can write simple modules, but I still don't get when __init__ 
needs to be used as opposed to creating a class instance by assignment. For 
some strange reason the literature seems to take this for granted. I'd 
appreciate any pointers or links that can help clarify this.

Thanks
