My fault :\ I said "thank you" to Rob, but I just sent a private message. It's just that I did a reply and not reply to all. Anyway, I RTFM and solved my problem :) Thanks again, Bye -- http://mail.python.org/mailman/listinfo/python-list

Kind of odd. Someone involved in the language they're having trouble with wrote some documentation for the exact thing they're asking for, you tell them where it is, and that doesn't deserve thanks? Something's wrong here. Well, it's about time for that which must be read by everyone on the Internet to be mentioned again.

re.compile('a*b*$')
$ matches the end of a string, or in MULTILINE mode, the end of a line
(right before newline)
Symmetrically, ^ matches the start of a string, or in MULTILINE mode, the
start of a line (including the start of the string)

Read (and bookmark) this:
http://www.python.org/doc/2.5.2/lib/re-syntax.html
You want the 3rd item down about the "$" special character.
>>> p = re.compile('a*b*$')
>>> m = p.match('aabb')
>>> m is None
True
>>> m = p.match('aabbb')
>>> m.group()
'aabbb'

Exact match with regular expression
Hi,
I'd like to use regular expressions to parse a string and accept only
valid strings. What I mean is the possibility to check if the whole
string matches the regex.
So if I have:
>>> p = re.compile('a*b*')
I can match this: 'aabbb'
>>> m = p.match('aabbb')
>>> m.group()
'aabbb'
But I'd like to get None with this: 'aabb'
Instead it matches the first part:
>>> m = p.match('aabb')
>>> m.group()
'aab'
I know this is the expected behaviour, but I'm sure it should be
possible doing what I said.
Are there other methods I don't know about in the re module?
Thanks.
