Nope. re wouldn't help here - it works on strings, not on lists (you 
need to understand that in Python, strings are *not* 'lists of chars').

Use list comps:
   mylist = [item for item in mylist if item != '0024']

or filter() :
   mylist = filter(lambda item: item != '0024', mylist)

May I second Grant Edward's suggestion in previous thread ? You'd really 
do yourself a favor by following a couple Python tutorials. I'd say the 
one in the official doc, and Dive into Python.
