regular expressions...

I am having a very hard time getting ahold [mentally] of regular
expressions under Python. I have the following code in Perl which I
have been trying to duplicate in python:

##################################################
# Look for subject line and pull the subject out
# to see if its 'subscribe' or 'unsubscribe'
##################################################
#
if (/^Subject:(.*)/) {
$subject = $1;
$subject =~ s/^[ \t]*//;
$subscribing = scalar(grep(/^\s*subscribe/i,$subject));
$unsubscribing = scalar(grep(/^\s*unsubscribe/i,$subject));
}

Can anyone help me out here? I have read what little documentation
there is on regular expressions in Python, and since I am not an Emacs
guru I haven't been able to draw on any knowledge in that area...

Is there a way to use the regex.set_syntax call to make Pythons regex
behave more like perl's? Has anyone written a perl regular expression
module for python?

If there is a WWW server with some decent documentation on the regular
expression syntax used in Python?

Thanks very much!
