What are your requirements?

If dmidecode is a command-line program, maybe something using os.popen:

#!/usr/bin/env python
import os

dmiOutput = os.popen("dmidecode", "r")

status = None
for line in dmiOutput:
    line = line.strip()
    if line.startswith("Status: "):
        status = line.split("Status: ", 1)[1]
        break

if status is not None:
    print "Status is: ", status
else:
    print "No status information found"
