import os
import re

def ping(ip, tries = 2):
    my_re = re.compile('(\w|\W)+ (\d) received, (\w|\W)+')
    for attempt in range(tries):
        ping_in, ping_out = os.popen2("ping -c 1 %s" % ip)
        for line in ping_out:
            rec_match = my_re.match(line)
            if not rec_match: continue
            received = int(rec_match.groups()[1])
            if not received: continue
            return attempt + 1
    return False

it takes an optional second argument (# of tries) and returns the number of
tries needed when successful, False otherwise.  the SMTP stuff can be handled
with smtplib.  it's part of the standard library.  the main python site has
pretty good documentation on this, including example code:
