The task doesn't want to be solved
I don't understand why, but when I click the "check solution" button, the site shows an error, although the code works if I just run it.
def split_pairs(a): splitted_word = list(a) result = [] counter = 0 while True: if len(splitted_word) == counter: break elif splitted_word[counter] == splitted_word[-1]: result.append(splitted_word[counter] + '_') break else: result.append(splitted_word[counter] + splitted_word[counter + 1]) counter += 2 return result
