For the question: What is the output of this code? sqs = [0, 1, 4, 9, 16, 25, 36, 49, 64, 81] print(sqs[1::4]),

why is the answer [1,25,81]

The result is 1, 25, 81 because sqs[1::4] means return every fourth element begining with index 1

Hiral Jain [2:5:3] means return every 3rd element starting from index 2 to index 4 (excluding 5) ,so you only get 4 because 25 (the next 3rd element is at index 5)

Hiral Jain slice in python works like this: [start:stop:step] where: -start is the start index -stop is the final index-1 -step is the increment step The slice method is a short for method.

If I were to print(squares[2:5:3]), why is the last index term not included i.e. answer is [4] and not [4, 25]
