Hi, I am rather confused by these results below. I am not a re expert at all. the module version of re is 2.2.1 with python 3.1.2
>>> import re
>>> re.findall('.a.', 'Mary has a lamb') #OK
['Mar', 'has', ' a ', 'lam']
>>> re.findall('(.a.)*', 'Mary has a lamb') #??
['Mar', '', '', 'lam', '', '']
>>> re.findall('(.a.)+', 'Mary has a lamb') #??
['Mar', 'lam']
Thanks in advance for any comments.
