Output of the below code and why is that output printed?

Question

squares=[0,1,4,8,64,81]
print(squares[1:1:-1])

Can some please explain me What is the output of the code and why?

Answer 1

Output is : []
an empty list.

Beacause, in normal slicing [1:1] is also an empty one. Now you cannot reverse an empty list. So, -1 is useless here.

Answer 2

Thanks Abhay . next time sure i will post with an answer and ask for explanation.
