How to slice the following code

Question

In python:

Use the slicing syntax of lists to get every other entry in the following list starting at the beginning and print the results.

['a','b','c','d','e','f','g']

Sample output:

['a', 'c', 'e', 'g']

Answer 1

this is all you need

input = ['a', 'b', 'c', 'd', 'e', 'f', 'g']

print(input[::2])

The syntax for slicing goes, [<start>:<end>:<step>]

Since we don't set a start or an end, the slice will encompass the entire array. But by setting the step to 2, we utilize the elements starting at index 0, then step forward 2 indexes and use that element, then keep stepping forward 2 indexes repeatedly until we run out of elements in our array. Thus we will use every other elements in our input list
