Hi,

They don't need to be explicitly called, no. (You can if you want, but tbh it makes the code rather awkward.) The intent is just for you to make use of the logic you came up with while implementing the Caesar functions – my apologies, the spec could be clearer on that point. You could if you liked split out the 'Caesar' bit of the Vigenere implementation into a separate 'helper' function if you like, but really, it should only come to a line or two of code so probably isn't worth it.

I hope that helps! Let me know if anything is not clear.

Cheers,

Arran

Hi Arran,

In the project spec it says the following: We will first implement the Caesar cipher (functions caesar_encrypt and caesar_decrypt), and then make use of those functions to implement the Vigenere cipher.

I want to know whether the caesar_encrypt and caesar_decrypt functions need to be explicitly called within our vigenere_encrypt and vigenere_decrypt functions, or if we are just supposed to apply the logic of the Caesar cipher in the Vigenere cipher functions without directly calling the Caesar functions?

Thanks
