Tell us what’s happening:

I dont understand what is going on here, need help

Your code so far

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

# User Editable Region

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

Hi @Soul1,

The instructions wants you to use an addition operator (+=) for the variable encrypted_text which will produce the same result as encrypted_text = encrypted_text + alphabet[new_index].

As the example showed, a = a + b is what you currently have with encrypted_text = encrypted_text + alphabet[new_index].

So the question for this step is, how would you make encrypted_text = encrypted_text + alphabet[new_index] look like a += b?

I hope this helps some. Happy coding!
