Learn String Manipulation by Building a Cipher - Step 89

Tell us what’s happening:

Describe your issue in detail here.
I swear I have it right but I’m not sure. The outcome is what the step told me but says that it’s wrong. Says this: You should have a print() call that prints Key: python by concatenating the string 'Key: ' and the value of the custom_key variable

Your code so far

text = 'mrttaqrhknsw ih puggrur'
custom_key = 'python'

def vigenere(message, key, direction=1):
    key_index = 0
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    final_message = ''

    for char in message.lower():

        # Append any non-letter character to the message
        if not char.isalpha():
            final_message += char
        else:        
            # Find the right key character to encode/decode
            key_char = key[key_index % len(key)]
            key_index += 1

            # Define the offset and the encrypted/decrypted letter
            offset = alphabet.index(key_char)
            index = alphabet.find(char)
            new_index = (index + offset*direction) % len(alphabet)
            final_message += alphabet[new_index]
    
    return final_message

def encrypt(message, key):
    return vigenere(message, key)
    
def decrypt(message, key):
    return vigenere(message, key, -1)

# User Editable Region

print('Encrypted text: ' + text)
print('key: '+ custom_key)

# User Editable Region

#decryption = decrypt(encryption, custom_key)
#print(decryption)

Learning to describe problems is hard, but it is an important part of learning how to code.
Also, the more you say, the more we can help!

Make it Key, uppercase K

wow it was that simple. Appreciate!
