What do these lines print?>>> a = [1, 2, 3, 4]>>> a[-1]-124[4, 3, 2, 1]

The code you've provided 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 the elements 1, 2, 3, and 4.

2. a[-1] - This line is accessing the last element of the list 'a', which is 4.

3. -124 - This line is just a negative number, -124.

4. [4, 3, 2, 1] - This is another list with the elements 4, 3, 2, and 1.

However, these lines of code are not connected in any way and will not print anything as they are. If you could provide a bit more context or clarify what you're asking, I'd be happy to help further!
