Where is the issue – I am lost as to what the error is here. Thank you in advance.
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
# User Editable Region
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)
# User Editable Region
index = alphabet.find(char)
new_index = (index + offset) % len(alphabet)
encrypted_text += alphabet[new_index]
print('plain text:', message)
print('encrypted text:', encrypted_text)
