So don't use Python idioms in BASIC. :) Back when I used to write
BASIC code, I'd do explicit comparisons with zero for this sort of
thing... these days, I'd use Python idioms, but I'd also write Python
code :)
I think it's indicative that the BASIC code I'm most proud of was
consciously getting around language limitations (I wrote a mess of
code in assembly language and Q-BASIC to allow my programs to use the
mouse), but the Python code I'm most proud of is using the language's
strengths.
