Learn String Manipulation by Building a Cipher - Step 57

I don’t know what i am doing wrong

Your code so far


text = 'Hello Zaira'
custom_key = 'python'

def vigenere(message, key):
    key_index = key[key_index % len(key)]
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    encrypted_text = ''

    for char in message.lower():

# User Editable Region

        # Append space to the message
        if char == ' ':
            encrypted_text += char
        else:
            key_char = 'key'

# User Editable Region

            index = key[key_index % len(key)]
            new_index = (index + offset) % len(alphabet)
            encrypted_text += alphabet[new_index]
    print('plain text:', message)
    print('encrypted text:', encrypted_text)

you don’t need to create a string 'key', please try reading again carefully the instructions

but this was the instruction,
inside the else block, declare a variable called key_char and assign it the value of key
and when i removed it,i was told to declare the variable called as key_char

you have a key variable that you need to use here, you should not create a string

thank you for your reponse, but i am still lost here

coding is difficult, yes
do it one step at a time

  1. declare a variable called key_char
  2. assign it the value of key
  3. assign it the value of key at the index key_index
  4. assign it the value of key at the index key_index mod(% ) the length of key .

Let’s do the first two steps for now, ok? Show me what you would write for that
