Tell us what’s happening:

Describe your issue in detail here.

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():
    
        # 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

Learning to describe problems is hard, but it is an important part of learning how to code.

The step requests is asking:

Call your function passing text and custom_key as the arguments. Store the return value of the function call in a variable called encryption.

To call a function in Python means to write only the name of the function (without the keyword def). When you call a function it is possible that it returns something, which it is asking to save in another variable named encryption.
Here the format

returned_value = called_function(first_argument, second_argument)
