Yes, well ... as you've probably figured out I'm kind of new to Python,
and I'm not too sure I understand the way that Python handles regular
expressions.  What actually happens when one "compiles" a regular
expression?

If I want to extract lines from a file that begin with numerical data for
instance would I do something like:

    pattern = regex.compile('^[0-9]']

    for line in open(filename, 'r').readlines():
      
       if pattern.match(line):
          print line
