You would?
I have only been using python for 6 - 12 months but in my past I 
programmed microcontrollers in assembly.

as soon as i saw it i understood it & thought great, like a light bulb 
going on.

I suppose I have the advantage that it is only the taint of BASIC (in the 
home computer era) that I have had to overcome and my programming style 
has not been unduly influenced by c & others.

it is easy to write C, or Pascal or even BASIC in python but why bother, 
why not just use C, Pascal or BASIC in that case?
