am i putting += on the right line ?

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)

Yes, but you can’t have = and += in the same line/expression. You would transform an expression with += like this:

a = a + b
a += b

These are equivalent. Notice it does not become:

a = a += b #incorrect

Transform this in the same way:

encrypted_text = encrypted_text + alphabet[new_index]
