Learn String Manipulation by Building a Cipher - Step 58

Tell us what’s happening:

stuck help
added += 1 to key index

Your code so far


text = 'Hello Zaira'
custom_key = 'python'

def vigenere(message, key):
    key_index = 0
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    encrypted_text = ''

    for char in message.lower():

/* User Editable Region */

        # Append space to the message
        if char == ' ':
            encrypted_text += char
        else:
            key_char = key[key_index += 1 % len(key)]
            


/* User Editable Region */

            index = alphabet.find(char)
            new_index = (index + offset) % len(alphabet)
            encrypted_text += alphabet[new_index]
    print('plain text:', message)
    print('encrypted text:', encrypted_text)

This is not valid. You should not modify that line. You need to increment key_index by 1 in a new line.

i tried adding

key_char += 1

to incement it after the else but is not working

sorry not key_char but

key_index +=1

Can you share the whole code again?
