python3 regex support

[DeaD_EyE]

Don't use reqex for this task.

A solution without using regex and relying that the output format does not change.

def parse(line):
    date, user, nas_ip, frame_ip, station, reply, port = line.split(',')
    date = datetime.datetime.strptime(date, '%d-%m-%Y_%H:%M:%S')
    user = user.replace('User-name=', '')
    nas_ip = nas_ip.replace('NAS-IP-Address=', '')
    frame_ip = frame_ip.replace('Framed-IP-Address=', '')
    station = station.replace('Calling-Station-Id=', '')
    reply = reply.replace('Reply-Mesasge=', '')
    port = port.replace('NAS-Port-Id=', '').rstrip(';')
    port_attr = {}
    for item in port.split(';'):
        key, value = item.split('=')
        port_attr[key] = int(value)
    return {
        'date': date, 'user': user,
        'nas_ip': nas_ip, 'frame_ip': frame_ip,
        'station': station, 'reply': reply,
        'port': port_attr,
        }

Output:
{'date': datetime.datetime(2019, 3, 11, 18, 43, 14),
 'user': '4841605613',
 'nas_ip': '10.124.113.246',
 'frame_ip': '',
 'station': '14:a7:2b:03:5f:23',
 'reply': 'Authentication Failed due to Invalid Password',
 'port': {'slot': 3,
  'subslot': 2,
  'port': 100,
  'vlanid': 2160,
  'vlanid2': 1284}}

Maybe the parsing of datetime is not right. Check the format. Maybe month and day is swapped.
