Exam PCEP-30-02 topic 1 question 9 discussion

The output of the code snippet is: [1, 3, 5, 7, 9] Explanation: a[::2] uses Python slicing syntax: The first : indicates the starting point (default is the beginning of the list). The second : indicates the stopping point (default is the end of the list). The 2 after the second colon is the step size, which means it skips every second element. Starting from the first element (1), it selects every second element: 1, 3, 5, 7, 9.

a = [1,2,3,4,5,6,7,8,9] print(a[::2]) >> printing the whole list a by the step 2 >> a[0], a[2], a[4], a[6], a[8], remeber to start counting from 0

a is the correct answer

[start : stop : step] inclusive, exclusive respectively
