Am I missing something obvious here?
just split on ','
field [0] will contain a mix of data but who cares? you don't want it
anyway (you can always process it again afterwards.
>>> a='192.168.1.6 > 192.168.1.7: ICMP echo request, id 100, seq 200,
length 30'
>>> data=a.split(',')
>>> data
['192.168.1.6 > 192.168.1.7: ICMP echo request', ' id 100', ' seq 200', '
length 30']
>>> data[3]
' length 30'
