Python search for value in string

I have a string like this:

STAT bytes 0
STAT curr_items 0
STAT total_items 0
STAT evictions 0
STAT reclaimed 0
END

I'm trying to get the value of curr_items, so far I've got 

out = telnet.read_until("END")
req = re.search("curr_items", out).group(0).split()[0]

Which returns curr_items, how do I get the value?

Thanks

try:
    req = int(re.search("(?<=curr_items)\s*([\d]*)", out).group(0))
except:
    # No value was found.
    req = defaultValue

re.search("curr_items [0-9]*", out).group(0).split()[1]

You can add a capture group matching the value to your regex:

>>> int(re.search("curr_items (\d+)", out).group(1))
0
