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]),

Question

why is the answer [1,25,81]

Answer 1

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

Answer 2

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)

Answer 3

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.
