why the answer of this code is [0, 1, 4, 9, 16, 25, 36, 49, 64] and not [0, 1, 4, 9, 16, 25, 36, 49, 64, 81] and iam remember that -1 starts from the last no. in the list , then why the answer is not include 81????

Question

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

answer

[0, 1, 4, 9, 16, 25, 36, 49, 64]

Answer 1

first number is always 0. Try to print(squares[0:-1])

Answer 2

by standard the python dont include the last index , just the first one, this serves for tuples too. then, ever you slice a list, the second index won't be returned.

Answer 3

But answer will be 1,4,9,16,25,36,49,64
