Have a look at your if-statements. It is possible, that both your if's
are executed in one loop iteration (you can check this using pdb). You
may want to try elif instead.

With:

Than:

But to increase speed it's usually better to reduce memory

It's just like in algebra. You evaluate exponents before the - which, after
all, is just another way to write -1, or times-negative-one. However, a

I've been working in the shell on and off all day, and need to see if
a function I defined earlier is defined in the current shell I'm
working in.
Is there a shell command to get of list of functions I've defined?
TIA!
P.S. If it makes a difference, I'm using the shell from within IDLE,
but
Everyone,
I'm pleased to annouce that a new version of GMPY is available.

Leaving iteration names bound after loop exit is a feature. If you do
not like it, explicitly unbind it.

Yikes. Thanks very much. Python seems to act unlike other language in
which words like float are reserved. I'll use asum.
The problem is that there is a function sum and you creating a float sum:
