Tell us what’s happening:
I have tried everything I can think of, but I get an error saying:
“You should multiply offset
by direction
in the new_index
assignment. Do not add other parentheses.”
My answer is: new_index = offset * direction
How should I fix it?
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)
