The ^ means begining of line EXCEPT inside a charachter class. There it means NOT for the entire class and it only means that if it is the very first charachter. I suppose you could consider that the there are two separate types of char classes. One is started with [ and the other is started with [^. > > > > > That would be \ > > > > Here's where I'm confused. From the Python docs: > > Special characters are not active inside sets.

This is indicated by including a "^" as the first character of the class; "^" elsewhere will simply match the "^" character. For example, [^5] will match any character except "5". _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
