Let's analyze the code step by step:
Initialization of the list:
my_list = [3, 1, -1]
At this point, my_list is [3, 1, -1].
Assignment operation:
my_list[-1] = my_list[-2]
Here:
my_list[-1] refers to the last element of the list (-1).
my_list[-2] refers to the second-to-last element of the list (1).
The operation assigns the value of my_list[-2] (which is 1) to my_list[-1].
After this, the list becomes [3, 1, 1].
Print the list:
print(my_list)
The output is [3, 1, 1].
Final Output:
[3, 1, 1]
The code performs the following operations:
my_list = [3, 1, -1] initializes a list with the elements [3, 1, -1].
my_list[-1] = my_list[-2] assigns the value of the second last element in the list (my_list[-2]) to the last element (my_list[-1]). Since my_list[-2] is 1, the list becomes [3, 1, 1].
print(my_list) prints the updated list.
The output will be: [3,1,1]
