### Your code so far

```py

# User Editable Region

text = 'Hello World'
shift = 3
alphabet = 'abcdefghijklmnopqrstuvwxyz'
encrypted_text = ''

for char in text.lower():
    print(char == '')
    index = alphabet.find(char)
    new_index = index + shift
    encrypted_text += alphabet[new_index]
    print('char:', char, 'encrypted text:', encrypted_text)

hay una diferencia entre tu código y las instrucciones

> comparing `char` with an empty space (`' '` ).

este es el espacio vacio que tienes que comparar

```auto
' '

```

esto es lo que estás comparando en tu código

```auto
''

```
