Tell us what’s happening:
You should change each occurrence of encrypted_text into final_message. is what the website said, where is the last one??Help me find it. =))
My code so far
text = 'Hello Zaira'
custom_key = 'python'
# User Editable Region
def vigenere(message, key, direction):
key_index = 0
alphabet = 'abcdefghijklmnopqrstuvwxyz'
final_massage = ''
for char in message.lower():
# Append space to the message
if char == ' ':
final_massage += 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*direction) % len(alphabet)
final_massage += alphabet[new_index]
return final_massage
# User Editable Region
encryption = vigenere(text, custom_key, 1)
print(encryption)
decryption = vigenere(encryption, custom_key, -1)
print(decryption)
