Your example is just string manipulation. You're not combining regexps here, you are combining strings which you (evidently) will soon use to create a regexp. Yes, you can do that in Python as well, in exactly the same way, using Python's string manipulation capabilities. Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
