How about using numpy?

Thank's for all the replies! I've tried some of the imporovements you suggested
(using math.exp() and sum() or math.fsum()).
None of that made the code faster, because they are functions you are calling
lots of times, and function calling is quite time expensive (same as x**(1/2)
is faster than

No, you just need the layout part of QtCreator, called QtDesigner, and
any decent Python editor or IDE (e.g. Idle):

Hello
Every once in a while, my ISP's SMTP server refuses to send
perfectly legit e-mails because it considers them as SPAM.
So I'd like to install a dead-simple SMTP server on my XP computer
just to act as SMTP backup server.
All I'd need is to change the SMTP address in my e-mail client

What you're looking for is not an SMTP server but a Mail Transfer Agent,
called an MTA.
Pretty much all distros ship with an MTA by default, even if the SMTP

Thanks to everyone for their wealth of suggestions. I already had my students
playing with turtle. And I had asked them to alphabetize a string (without
having previously revealed the sorted() function).
So far, I have taken up the suggestion of the number-guessing game. One of my

Even if they don't, they'll grok it no problem. It's simple enough.

John, have you taken a look at pyglet? It's an alternative to pygame and I
found it pretty slick once I got the hang of it. There is a development
version that's compatible with python 3 and I've never had a bug with it. It
wraps OpenGL itself so there are no additional dependencies.
