###I am following the instruction given as I already know and double checked it many times.But it still displays an error saying: You should multiply offset by direction in the new_index assignment. My code so far shows that I«'m already doing it. What am I missing here?
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)
#print(encryption

If you want to reverse the encryption operation, should you just modify the value of offset from addition to subtraction, or rewrite the whole line like you did?
Think about what the line will do in either cases, then you may know what the instruction really means to do. Does it really mean to “just assign new_index to the multiplication of the two valuables”, or “just multiply offset by direction in the assignment line of new_index”?
Yes, it is something to think about. But the instruction says: “All you have to do is multiply the offset by the direction variable using the * operator in Python.” That kind of restrain my options.

hi @brunoahlc i’ve tried to add the multiplication of offset by direction to the existing line but still don’t pass.
new_index = (index + offset) % len(alphabet) + offset * direction
Please can you be more detailed on how you went about it? Or additional hints? Thanks.
