New Users Introduce Yourself

[Farrout]

New guy here, obviously.
Built (with components) my first PC in 1980.  Cromemco with Z80, 16K RAM,
two floppy drives.  Became pretty proficient in basic.
Python was recommended to me by an IT pro because I said I was going to
take some classes at the local Jr. college to learn Java.
I want to data mine some extremely large (50 gig) data sets and hope this
will be easier to learn. It kind of reminds me of basic.
Anyway, reading lots of tutorials, trying things.
I've gotten to the point that I can write a module, and import it, and it runs, once.
Still trying to find out what to do to make it run again without closing python, then starting over.
I'll try not to be a pest.  

Thanks
Dennis
