Why are not taking last indexing number?

Question

squares = [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
print(squares[2:6])

[4,9,16,25]

Why are not taking 6 indexing number (36)

Answer 1

start index is included but not the end
so if u have array[5:10]
it will give element start from index 5 till index 9
