Regex in Python - printing all matches

I've been dabbling in a bit of python. A good friend of mine, Michael, has given me a head start on this (http://benz.io/posts/Python-Regex/) - the re module is very nifty.

re.match can return a "None" or matched result using Michael's example, so we can perform boolean checks on the data

import re
a = re.compile("^.*[0-9]")

result = a.match("Michael")
if result != None:
    print "Match!"
else:
    print "No Match :("

If however you want to print all matches (equivalent to something like grep {regex-statement} ) you can use re.findall to achieve this

import re
def get_NY_cobbler_hosts():
    hosts = subprocess.check_output(['cobbler', 'system', 'list'])
    ### Assuming all new-york hostnames begin with "ny"
	hostlist = list(re.findall('ny.*', hosts))
	return hostlist
