of equal length, and adds them together? For example,

Sorry, meant try/except (I was thinking VFP).
Wouldn't if/else be more difficult when validating if an input is a

Hi Okechukwu,
I would recommend to use Khan Academy. It is free resource of use.
He covers python basic plus they built sophisticated system that track
