#!/usr/bin/env python

#fixed the import, just red PEP 8
import re 
###################################################
def extract(data):
    ms = re.match(r'(\S+).*mid:(\d+)' , data) # heure & mid 
    k = re.findall(r"/(\S+)", data) # source & destination  
    exp = result = re.findall(r'NVS:([\w\.]+)',data) # type S & D
    # if the table length is 1 it means that the origin is unknown
    if len(k)==1:
      return {'Heure':ms.group(1), 'mid':ms.group(2),"Origine":"Unknown","Destination":k[0],"Type S":exp[0],"Type D":exp[1]}
    # if the table length it means that there's a a source and a destination
    if len(k)==2:
      return {'Heure':ms.group(1), 'mid':ms.group(2),"Origine":k[0],"Destination":k[1],"Type S":exp[0],"Type D":exp[1]}

well the issue is that when i have lines like that where there's [NVS:FAXG3.1.0/+44614215421] it returns None, is there way to make is stop at the second NVS: so that it stopps like if we have a line like data2

data = "13:16:16.146 mta         Messages       I CC Doc O:NVS:SMTP/[email protected] R:NVS:SMTP.0/[email protected] [NVS:FAXG3.1.0/+44614215421] mid:41414"
print extract(data)

It returns

>>>None

data2 = "13:16:16.146 mta         Messages       I CC Doc O:NVS:SMTP/[email protected] R:NVS:SMTP.0/[email protected]  mid:41414"
print extract(data2)

It returns

>>> {'Destination': '[email protected]', 'mid': '41414', 'Type S': 'SMTP', 'Origine': '[email protected]', 'Type D': 'SMTP.0', 'Heure': '13:16:16.146'}

Dirty hack

Just replace

if len(k)==2:

to

if len(k)>1:

because it found more than 2 matches in the second string
