Hi team. I need help with the return value of the function. I tried to assign it to the variable. It returned an error.
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
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) % len(alphabet)
encrypted_text += alphabet[new_index]
return encrypted_text
/* User Editable Region */
vigenere(text,custom_key)
return encryption = 'text', 'custom_key'
/* User Editable Region */

Call your function passing text and custom_key as the arguments. Store the return value of the function call in a variable called encryption .
You have called the function correctly but perhaps the second part of the instruction is a little confusing. Calling the function generates a return value, so you just need to assign the function call to the new variable (i.e. in the form variable = function_call).
So for a bit of context the return keyword is used inside a function to give you a variable back when you call the function.
For example
def give_int():
return 5
means that whenever you run the give_int function you get 5 back.
Now to assign that to a variable you would do something like:
int_var = give_int()
Which would now be the same as int_var = 5.
So with that knowledge, you already have return encrypted_text in your vigenere function. Which means if you call it, you get the encrypted text. To now assign this to your variable you can use:
