Question

A = [1, 2, 3, 4, 5] Что отображается на экране? print (a [-2 :))

Answer 1

A = [1, 2, 3, 4, 5]

# print(a[-2]) - Выдаст ошибку.

print(A[-2]) - Выведет 4.

Потому то идет отсчет в обратную сторону.

[1, 2, 3, 4, 5]

                 ↑

[1, 2, 3, 4, 5]

            ↑

Answer 2

Looks like you're using a mix of Russian and English. Let's clarify your question.

You've defined a list A = [1, 2, 3, 4, 5].

Then you're trying to print a slice of this list using print(a[-2:]).

However, there's a typo in your code. You're using a lowercase 'a' instead of an uppercase 'A'. The variable you defined is A, not a.

So, the correct code would be:

pythonCopy code
A = [1, 2, 3, 4, 5]
print(A[-2:])

This will output:

csharpCopy code
[4, 5]
