"myexpression" won't return "AZBaCTR" for any kind of input, so I'm not
sure what "of course" really refers to...

my guess is that you're using "*" or "+" in a situation where you don't really
need them. cf.
>>> re.findall("\w", "abcdef")
['a', 'b', 'c', 'd', 'e', 'f']
>>> re.findall("\w+", "abcdef")
