A shuffled playlist alternates between your songs and a friend's. Write every_other(playlist) that returns a new list containing the songs at positions 0, 2, 4, ... (yours), in order.
Examples
Input: playlist = ["a", "b", "c", "d", "e"]
Output: ["a", "c", "e"]
Input: playlist = ["x", "y"]
Output: ["x"]
Constraints
0 <= len(playlist) <= 5000
Goals
- Select items at even positions
- Use a slice step or a loop with a stride of 2
