Tell us what’s happening:

i called direction in the defined function still there’s an error

Your code so far


# User Editable Region

text = 'Hello Zaira'
custom_key = 'python'

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

    for char in message.lower():
    
        # Append space to the message
        if char == ' ':
            encrypted_text += char
        else:        
            # Find the right key character to encode
            key_char = key[key_index % len(key)]
            key_index += 1

            # Define the offset and the encrypted letter
            offset = alphabet.index(key_char)
            index = alphabet.find(char)
            new_index = (index + offset) % len(alphabet)
            encrypted_text += alphabet[new_index]
    
    return encrypted_text
    
# encryption = vigenere(text, custom_key,)
# print(encryption)

Hi there and welcome to our community!

Slightly odd error with the tests, but you have a stray comma after custom_key in this commented out line. If you remove it, your code should pass.

why does that comma in the commented line affect the code?
btw thanks!!

It shouldn’t do… I guess the tests are looking for the comments to match exactly what is expected?

yes, there isn’t a way to test comments other than regex

if you want to suggest a different approach, like maybe the absence of the two lines from the code, you can open a github issue about it, please
