Tell us what’s happening:

I don’t know how to solve it , so could you please help me ? thanks in advance

Your code so far

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)



# User Editable Region

            new_index = offset * direction

# User Editable Region

            encrypted_text += alphabet[new_index]
    
    return encrypted_text
    
encryption = vigenere(text, custom_key ,1)
print(encryption)

Hi. You have deleted the existing seed code when you need to add to it. I suggest you reset the step and try again, carefully following the instructions.
