Hi Terry,
For my money, and especially in your versions, despite several expert solutions
using other features, itertools has it. It seems to me to need less nutting out
than the other approaches. It's short, robust, has a minimum of symbols, uses
simple expressions and is not overly clever. If we could just get used to using
takewhile.
takewhile mines for gold at the start of a sequence, dropwhile drops the dross
at the start of a sequence.
Thanks all for your interest and your help,
Best,
Nick
