finditer compiles the regex for you, of course, and caches the
result. but if you really want to do it yourself, just do it:
>>> p = re.compile("([a-z]W)")
>>> p.finditer("aWbWcXdXeWfY")
<callable-iterator object at 0x009249B0>
>>> for x in p.finditer("aWbWcXdXeWfY"):
... print x.groups()
...
('aW',)
('bW',)
('eW',)
