My curent code which works for bellow format :

#Feb  7 07:33:19 xxxx yum[17961]: Installed: vsftpd-2.2.2-14.el6.x86_64
get_date = re.compile('([A-Z-a-z]+ [0-9]+ [0-9]+:[0-9]+:[0-9]+)(.*)')


current_time = datetime.datetime.now()
lastHourTime = datetime.datetime.now() - datetime.timedelta(hours = 1)

def _read_log():

        with open (LOG_FILE,'r')as f:
                content=f.readlines()
        return content

if __name__ == '__main__':
        log_file=_read_log()
        last_execution_time=_get_last_log_time()
        for line in log_file:
                #GEt the Date only from the log file Feb  7 07:33:19
                match=re.search(get_date,line)
                if match:
                  #Capture only the date field so taht we can compare iet
with (current_time and lastHourTime.
                  #log_date= match.group(1).rstrip()
                  log_date =
datetime.datetime.strptime(match.group(1).rstrip(), "%b %d
%H:%M:%S").replace(year=datetime.date.today().year)
                  #log_date='Feb  7 07:33:19'

                  #print ('Log Date %s' %log_date)
                  #Check if log_date is greater then lastHourTime and less
then current_time
                  if  log_date < current_time and log_date > lastHourTime  :
                        new_log.append(line)

        print new_log

any help will be really appreciate
Thanks
