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 should call vigenere passing text and custom_key as the arguments.
({ test: () => assert.match(code, /vigenere\s*\(\s*text\s*,\s*custom_key\s*\)/) })
You should have an encryption variable.
({ test: () => assert(__userGlobals.has("encryption")) })
You should assign your function call to the encryption variable.
({ test: () => assert.match(code, /encryption\s*=\s*vigenere\s*\(\s*text\s*,\s*custom_key\s*\)/) })
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
