unable to convert text file in dictionary

[purnima1]

As mention key will be overwritten because of key collision.
Can use defaultdict which can collect values in a list.

Output:
CC_FIPS FULL_NAME_ND
AN    Aixas

AN    Aixirivall

AN    Andorra la Vella

AF    Biland

AF    Biland Hawa

from collections import defaultdict

d = defaultdict(list)
with open('to_dict.txt') as f:
    next(f)
    for line in f:
        line = line.strip()
        line = line.split(' '*3)
        if not line == ['']:
            d[line[0]].append(line[1].strip())

Test:

>>> d
defaultdict(<class 'list'>,
            {'AF': ['Biland', 'Biland Hawa'],
             'AN': ['Aixas', 'Aixirivall', 'Andorra la Vella']})
>>> d['AF']
['Biland', 'Biland Hawa']

I was running this code but getting error :
IndexError: list index out of range
