lines = i.split(";")[2] 

the problem of lines have 1 column or two, gives me 'index out of range' error. please tell me how go problem?

thanks lot adia

use slice instead of index.

>>> open('test.txt') f_in: ...     column3 = (line.split(';')[2:3] line in f_in) ...     column3 = [item[0] item in column3 if item] ...  >>> column3 [' green', ' orange', ' white', ' green', ' white', ' orange']
