My Python solution:
def encode(st): vowel_to_num = {'a': '1', 'e': '2', 'i': '3', 'o': '4', 'u': '5'} return ''.join(vowel_to_num.get(char, char) for char in st) def decode(st): num_to_vowel = {'1': 'a', '2': 'e', '3': 'i', '4': 'o', '5': 'u'} return ''.join(num_to_vowel.get(char, char) for char in st)
