Sure, there is.  With regular expressions (as shown previously); regular
expressions are deep juju. With split (if you just want to break things up;
as shown previously; your comma separated data is a natural for split ;-)
and with index, which returns the position of the first occurance of a
substring within a string.  An optional argument tells index where to start
looking.

It's cohort, rindex, returns the position of the _last_ occurence of a
given substring in a given string.

TMTOWTDI, after all...

For this particular application, no, probably not :-) But if that's what
you're used to, then, maybe...
