python get every even element code example

Example 1: every second value python

import numpy as np
values=np.arange(0,10)
print(values[::2])

Example 2: Try out the enumerate function for yourself in this quick exercise. Complete the skip_elements function to return every other element from the list, this time using the enumerate function to check if an element is on an even position or an odd position.

def altElement(a):
    return a[::2]
