Count number of occurrences in a log file

I'm trying to count the number of occurrences of multiple text patterns in a log file.

My code is counting all the lines in the file for all text patterns.

Where am I going wrong?

The log file looks like this:

  

Feb 1 00:00:02 bridge kernel: INBOUND TCP: IN = br0 PHYSIN = eth0 OUT = br0> PHYSOUT = eth1 SRC = XXX.XXX.XXX.XXX DST = XXX.XXX.XXX.XXX LEN = 40 TOS = 0x00> PREC = 0x00 TTL = 110 ID = 12973 PROTO = TCP SPT = 220 DPT = 6129 WINDOW = 16384 RES = 0x00> SYN URGP = 0
  Feb 1 00:00:02 bridge kernel: INBOUND TCP: IN = br0 PHYSIN = eth0 OUT = br0> PHYSOUT = eth1 SRC = XXX.XXX.XXX.XXX DST = XXX.XXX.XXX.XXX LEN = 40 TOS = 0x00> PREC = 0x00 TTL = 113 ID = 27095 PROTO = TCP SPT = 220 DPT = 6129 WINDOW = 16384 RES = 0x00> SYN URGP = 0

My code at the moment looks like this:

#!//usr/bin/python3

import sys
import os
import re

tipos= set()
cnt=0
p= re.compile ('bridge kernel:.*:')
with open (sys.argv[1], 'r') as f:
    for line in f:
        match = p.search(line)
        if match:
            taux=(line.split(":") [3])
            tipos.add(taux)
        if taux in tipos:
            cnt+=1
        elif taux not in tipos:
            cnt=0
        d=dict.fromkeys(tipos,contador)
print (d)
