Why it is returning output as n

I have come across one question during where the person ask me
what is the output of this below code

Code :

names = ['Chris', 'Jack', 'John', 'Daman']
print(names[-1][-1])

Then i said the answer will be : John

But the person who was interviewing he said the answer is 'n'

Can some one illustrate how it is n

>Solution :

The [-1][-1] is not [-2] at all.

Take the last word, then its last letter

>> names  
['Chris', 'Jack', 'John', 'Daman']
>> names[-1]
'Daman'
>> names[-1][-1]
'n'                # 'n' of Daman
>> names[-1][-2]
'a'                # last 'a' of Daman
>> names[0][1]
'h'                # 'h' of Chris
