User input

message = input("Enter your message: ") shift_value = int(input("Enter shift value (integer): ")) operation = input("Type 'encrypt' to encrypt or 'decrypt' to decrypt: ").lower()

Perform operation

if operation in ["encrypt", "decrypt"]: output_message = caesar_cipher(message, shift_value, operation) print(f"The {operation}ed message: {output_message}") else: print("Invalid operation selected.")
