I think this shouldn't put here, this code block is for explaining Lists, tuples, and strings accept an index or a slice:, not Dictionaries accept any hashable value.

If we want to add a new example for dictionaries, it should make a new code block above this one.

Actually, this makes the example exactly parallel the paragraph it follows, showing the dictionary example first, then the index, and then the slice, in the order they are mentioned in the text. Breaking the paragraph up with the example would not improve the flow, in my opinion. The fact that dictionary is in a separate sentence doesn't matter that much, I think.

'tu'
>>> itemgetter(1)('ABCDEFG')
'B'
>>> itemgetter(1,3,5)('ABCDEFG')
