Python：访问列表中的多个元素

Question

I have the following list:

my_list = ["shanya", 1.2, 1, False, "test", 2, 3.3, True, "3", "4.0"]

But how do I access multiple elements in this list?

I know how to access one specific element (eg, my_list[1] gives me [1.2] ) and a range (eg, my_list[1:3] gives me [1.2, 1] ) but how do I get the first and third to last element?

["shanya", 1, False, "test", 2, 3.3, True, "3", "4.0"]

Answer 1

You can use itemgetter :

>>> from operator import itemgetter

>>> values = ["shanya", 1.2, 1, False, "test", 2, 3.3, True, "3", "4.0"]

>>> itemgetter(0, -3)(values)
('shanya', True)

Answer 2

Simply contact the sub-lists, like:

result = l[:1] + l[2:]

output:

['shanya', 1, False, 'test', 2, 3.3, True, '3', '4.0']
