Learn String Manipulation by Building a Cipher - Step 63

Tell us what’s happening:

My code currently is not passing, the error message I am receiving currently is (the += operator should add 1 to key_index inside the else clause.)I think I’ve done that correctly but still providing the same error. Can anyone assist with this issue?

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
            key_char = key[key_index % len(key)]
            Key_index += 1

# 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)
