Split Strings

• Complete the solution so that it splits the string Into pairs of two characters.
• If the string contains an odd number of characters then it should replace the missing second character of the final pair with an underscore ('_').

Examples:

solution('abc')  should return => ['ab', 'c_']
solution('abcdef') should return => ['ab', 'cd', 'ef']

My Solution:

def solution(s):
    step = 2
    if len(s) % 2 == 0:
        return  [s[index : index + step] for index in range(0, len(s), step)]
    else:
        odd_str = [s[index : index + step] for index in range(0, len(s), step)] 
        el = odd_str[-1] + '_'
        odd_str.pop()
        odd_str.append(el)
        return odd_str
