in pure python you can also write: # ------------------------------------------------- import re

However this is untested. But you get the idea ;) re is certainly faster then in-loops.

I didn't test it either, but note that "." is not a special character inside the [] pair and that a bare "-" as the first or last character stands for itself. So the string could be more clearly written (imho) as just: [^A-Za-z0-9._-] -- Dennis Nichols nichols@tradingconnections.com
