Hi, ALL,
I'm trying to process a file which has following lines:
192.168.1.6 > 192.168.1.7: ICMP echo request, id 100, seq 200, length 30
(this is the text file out of tcpdump)
Now I can esily split the line twice: once by ':' symbol to separate
address and the protocol information and the second time by ',' to get
information about the protocol.
However, I don't need all the protocol info. All I'm interested in is
the last field, which is length.
Is there a way to write something like this:
for data in f:
(address,traffic) = string.split(data, ':')
length = string.split(traffic, ',')[3]
I'm interesred in only one element, so why should care about everything else?
This can be easily done in Perl, but I'm stuck with Python now. ;-)
data="192.168.1.6 > 192.168.1.7: ICMP echo request, id 100, seq 200, length 30"
(add,traff) = data.split(':')
add
'192.168.1.6 > 192.168.1.7'
traff
' ICMP echo request, id 100, seq 200, length 30'
lenn = traff.split(',')
lenn = traff.split(',')[3]
lenn
' length 30'
What if I want field 2 and field 3? ("seq 200" and "length 30")
Thank you.

Please do a little work before asking such a trivial question, it's
hardly difficult from the interactive interpreter, particularly when you
already have an example to start with.
