The formatting does not work correctly. I have a dict with string representations of integers as keys, such as {'1': 'a'} and trying to format it this way: '{0[1]}' and KeyError occurs. But I think it should not as '{0[a]}'.format(a) works properly with a = {'a': '1'} and '{0[1]}'.format(a) works properly with a = {1: 'a'}. Adding quotation marks does not help, KeyError occurs with '"1"'.
