[Tutor] Weird situation in using .split() function

[Eric Walker]

The first few are out of range. Only have one \t so you only get col[0] and col[1]
 
 
['STAG2\tmiR-101', 'SMARCA1\tmiR-101',
'RAP2C\tmiR-101', 'DDX3Y\tmiR-101',

I have a list t and the elements are tab limited. 
there are 2 columns:
>>>t
['STAG2\tmiR-101', 'SMARCA1\tmiR-101',

'AGRN\tmiR-101\tmiR-144', 'EPB41\tmiR-101\tmiR-144',

'ST6GALNAC3\tmiR-101\tmiR-144',
'CAPZA1\tmiR-101\tmiR-144']
>>> for i in t:
 i = i.strip('')
 cols = i.split('\t')
 print cols[0]

 
STAG2
SMARCA1
RAP2C
DDX3Y
AGRN
EPB41
PUM1
KIAA1573
ST6GALNAC3
CAPZA1

>>> for i in t:

 print cols[1]

Traceback (most recent call last):

    print cols[2]

>>> for i in t:

['STAG2', 'miR-101']

['ST6GALNAC3', 'miR-101', 'miR-144']
['CAPZA1', 'miR-101', 'miR-144']


When I try to Print column 2 (0,1,2 which is miR-144)
elements why is it saying index out of range whern
miR-144 is already there. 

Can any one please help me. 

thanks
Srini
