Printing variable names

[Mike]

Thanks for the info.  That does clear up a few things for me.  

This is what I'm trying to accomplish:

Basically I have a list of pointers to functions (or whaterver it's called in 
Python).  Something like this:

commands = [func1, func2, ...funcN]

This is in a script that I use to test an embedded system through the comport.
I call the script with the command number (func1 etc...), which calls the
corresponding function, which sends a command to the embedded system.

I'd like to be able to call the script with --help and have it spit out
the list of commands (the names func1, func2 etc...).
