Welcome to the wonderful world of programming. Regular expressions are what they are because they are modeled after a certain theory - that of finite state automata and their correspondence to certain classes of grammars.
(except that Python regexps are not always regular, of course. and that back- tracking engines like the ones used in Perl and Python differs in subtle ways from "real" DFA-based engines, etc. but as long as you're looking at things from a proper distance, you're right, of course)
