How do I make this sorting case insensitive?

Question

def sortProfiles(p):
    return sorted(p, key=itemgetter('first_name'))

I have a list with dictionaries. This function allows me to sort them by their first_name. However, it's case-sensitive.

Answer 1

>>> from operator import itemgetter
>>> p = [{'fn':'bill'}, {'fn':'Bob'}, {'fn':'bobby'}]
>>> sorted(p, key=itemgetter('fn'))
[{'fn': 'Bob'}, {'fn': 'bill'}, {'fn': 'bobby'}]
>>> sorted(p, key=lambda x: x['fn'].lower())
[{'fn': 'bill'}, {'fn': 'Bob'}, {'fn': 'bobby'}]
>>>

Answer 2

Here's a way:

return sorted(p, key=lambda x: x['first_name'].lower())
