Quoting http://docs.python.org/library/re.html :
"""
'.'
(Dot.) In the default mode, this matches any character except a newline. If
the DOTALL flag has been specified, this matches any character including a
newline.
[...]
'\'
Either escapes special characters (permitting you to match characters like
'*', '?', and so forth), or signals a special sequence; special sequences
are discussed below.
"""
So you get the desired behaviour by escaping the dot:
>>> re.findall(r'([\w]+\.)','abdd.e3\45 dret.8dj st.jk')
['abdd.', 'dret.', 'st.']
>>> re.findall(r'([\w]+[.])','abdd.e3\45 dret.8dj st.jk')
['abdd.', 'dret.', 'st.']
(assuming that you left out the last match accidentally)
