What do these lines print?>>> a = [1, 2, 3, 4]>>> a[-3]-3[4, 3]2

The provided code seems to be a bit jumbled, but I'll try to break it down as best as I can.

1. a = [1, 2, 3, 4] - This line is creating a list named 'a' with four elements: 1, 2, 3, and 4.

2. a[-3] - This line is accessing the third element from the end of the list 'a'. In Python, negative indexing starts from the end of the list, so -1 would be the last element (4), -2 would be the second last element (3), and -3 would be the third last element (2).

3. -3 - This line on its own doesn't do anything in this context. It's just the negative integer -3.

4. [4, 3] - This line is creating a new list with two elements: 4 and 3.

5. 2 - This line on its own is just the integer 2.

Without any operations or print statements, these lines of code don't actually print anything. If you want to print the result of a[-3]-3, you would need to use a print statement like print(a[-3]-3). This would print the result of subtracting 3 from the third last element of the list 'a', which would be -1 (since 2 - 3 = -1).
