What is the Output of this Code, And explain why it Outputs from 1 to 64

Question

squares = [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
print(squares[1:-1])

Answer 1

List slicing notation: [start:stop:step]
It includes start value while stop isn't included.
Also, index value of -1 gives the last element of the list.
So, [1:-1] is same as [1:9].
Hence, it returns [1,.....,64]
