The Caesar Cipher is a substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet. Julius Caesar used this technique to send secret messages to his allies.

1. Run the Python script.
2. Choose whether to encrypt or decrypt a message.
3. Enter the message and the shift value.
4. Get the result!

Here is the result of encoding a Caesar Cipher-encrypted message:

Type 'encode' to encrypt, type 'decode' to decrypt:
encode
Type your message:
Hello
Type the shift number:
5
Here's the encoded result: mjqqt

Here is the result of decoding a Caesar Cipher-encrypted message:

Type 'encode' to encrypt, type 'decode' to decrypt:
decode
Type your message:
mjqqt
Type the shift number:
5
Here's the decoded result: hello
