Pulling specific words out of a line of a text file in python

Question

I'm a newbie python programmer and I'm doing some playing around with network coding. In order to check to see whether a connection to the default gateway of my router has occurred, I want to pull the gateway from my ipaddr file and turn it to a variable, however I can't get it to pull the column from a specific line, only the first line.

This is my code so far:

with open('ipaddr.txt', "r") as f:
    line=f.readlines()
    columns = [line.rstrip("\t") for line in f]
    print (line[22])
    print (line[18])
    print (line[26])
    f.close()

I want it to pull from column 39 onward on each of the above lines.

You are using rstrip where you should be using split. You are also reading the file twice readlines() and for line in f.

with open('ipaddr.txt', "r") as f:
    lines=f.readlines()
    table = [line.split("\t") for line in lines]
    print table[22][39:]
    print table[18][39:]
    print table[26][39:]
    f.close()
