See 'pydoc commands'. You could probably do with

pattern = "<grep pattern>"
cmd_status, count = commands.getstatusoutput("ps -ef|grep -c %s" % pattern)

for i in range(count):
    # do something count times

Note: you don't need wc -l after grep, because grep has '-c' switch. 

Note2: not tested, some typos etc may be present.
