Out of curiosity, I would like to see your program. There's always 
something to learn (and even more so for me, being a newbie)

At the moment, nothing :-s
I'm learning Phyton, and I thought that this would be an interesting 
challenge. For what I've seen, Tkinter's Canvas 'could possibly' do the 
job. I still have to try it out. In case that didn't work, I was 
thinking in looking through wxpython.

Yes, I thought that:
try:
    #function
exception:
    pass

At the moment, I have almost nothing. After John Fouhy's replies I have 
rewritten the few lines I had at least three times :o)
It will be simple, I intend to support viewing specific parts of the 
function (instead of a fixed view), multiple graphs, perhaps an option 
to save/load functions. I first made a program like this in Qbasic 4.5, 
and thought doing it again in Python with an interface and more advanced 
options may be very entretaining. :-) I can send you the source/exe if 
you want (sadly you can't choose what you want to see in the exe 
version, the function must be hard-coded).

Thanks
