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

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