[issue33103] Syntax to get multiple arbitrary items from an iterable

[AmjadHD]

Yes that's a way to do it but "a, b, c = my_list[1, 3, -1]" seems so pythonic 
and straight forward, it's like formatting, python had already 3 methods to do 
it when it introduced a 4th one (f-strings), easier is better especially in 
python.

[issue33103] Syntax to get multiple arbitrary items from an iterable

Raymond Hettinger  added the comment:

FWIW, there is already a way to do this but it involves the extra step of 
applying map() to a bound method:

>>> my_list = ["John", "Richard", "Alice", 1, True, 2.1, "End"]
>>> a, b, c = map(my_list.__getitem__, [1, 3, -1])
>>> a
'Richard'
>>> b
1
>>> c
'End'

Serhiy Storchaka  added the comment:

This syntax already is supported for dicts and NumPy arrays, but with different 
semantic.

>>> d = {(1, 2): 'foo'}
>>> d[1, 2]
'foo'
>>> a = numpy.array([[1, 2], [3, 4]])
>>> a[1, 0]
3
