Scott, this is the wrong place to be asking this.  Python-dev is used to 
discuss the development of the Python language.  A better place to look 
for an answer to your question is on comp.lang.python (which can also be 
reached through python-list@python.org ).

But, to just go ahead an answer your question, the Python standard 
library has several places where regexes are used.  You can search for 
``import re`` or ``from re import`` to find modules that use regexes.
