you are probably returning 5 as string, but should as int.

Can't pass the tests, but each time i can get the right odd int.

I get the same error "Extra zeroes handling" when I submit without known what to do next, also I cann't get the 10-th test case to find out what's wrong with my code.
splited_words = morseCode.split(' ')
decoded_string = ''
for word in splited_words:
splited_characters = word.split(' ')
for ch in splited_characters:
decoded_string += MORSE_CODE[ch]
decoded_string += ' '
return decoded_string.strip()
