Your code so far

text = 'Hello Zaira'
custom_key = 'python'

def vigenere(message, key):
    key_index = 0

        if char == ' ':
            encrypted_text += char
            key_char = key[key_index % len(key)]

# User Editable Region

            index = alphabet.find(char)
            new_index = (index + offset) % len(alphabet)
            encrypted_text += alphabet[new_index]
