Learn String Manipulation by Building a Cipher - Step 39

I feel like the code i wrote is correct but, it keeps giving me the message " You should use the += operator to add char to the current value of encrypted_text". I feel like i’ve done exactly as asked and im a little confused about what im doing wrong. any help would be greatly appreciated.

Your code so far

/* User Editable Region */

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

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

You want to add a real space, not the string “space”. And the real space is stored in char (if True) → so what do you want to add to encrypted_text?


ahh okay, so i should use char instead of ‘space!’ to add a literal space to my output, thank you!
