Here is another suggestion:
col = 2 # third column
filename = '4columns.txt'
third_column = [line[:-1].split('\t')[col] for line in open(filename,
'r')]
third_column now contains a list of items in the third column.
This solution is great for small files (up to a couple of thousand of
lines). Fo

You say you would like to "read" a specific column.

use the "split" method and plain old indexing:
for line in open("file.txt"):
columns = line.s

Hi,
I have a file containing four columns of data separated by tabs (\t)
and I'd like to read a specific column from it (say the third). Is
there any simple way to do this in Python?
I've found quite interesting the linecache module but unfortunately
that is (to my knowledge) only working on line
