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']

Task URL: Link

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

    just adding "_" to the original string gives you chance to use only one behavior

    def solution(s):
    if len(s) % 2 != 0:
        s = s + '_'
    return  [s[index : index + 2 ] for index in range(0, len(s), step)]
    Enter fullscreen mode Exit fullscreen mode

    creating a step variable is just needed if you want to change it somethimes, but it could require some changes to be implemented because the number of underscores depends on the rest of the division.
