Alternatively, you could .split() your string and not invoke the mechanisms dealing with regular expressions.
Is this considered stylistically sloppy in the event that the split results in a very long array? Sloppier than REs are to begin with? I think that the problem with [\A\d] is that \A is zero-length, which doesn't make sense in the context of []. Brackets aren't shorthand for "'or' a bunch of small things together" but rather "'or' a bunch of these single-character matches together" mike On Tue, 1 Feb 2005 13:30:44 -0500, Smith, Jeff <[EMAIL PROTECTED]> wrote: > Kent, > > I think \b will work for me since I was really looking for [\A\W] > anyway. > > That still doesn't answer the generalized question about something like > [\A\d] for instance. > > Thanks, > Jeff > > BTW, I was using raw strings although I forgot to put that in. > > -----Original Message----- > From: Kent Johnson [mailto:[EMAIL PROTECTED] > Sent: Tuesday, February 01, 2005 1:15 PM > Cc: Tutor@python.org > Subject: Re: [Tutor] Matching with beginning of the line in the > character set > > Smith, Jeff wrote: > > I want to match a string which is preceeded by a space or occurs at > > the beginning of the line.
