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
