Beginning Python (Video 32)

This video tutorial delves into the shift cipher, a simple encryption technique that shifts characters in the alphabet. The tutorial explains how to implement both encryption and decryption functions in Python, ensuring the wraparound of characters. The video also demonstrates testing the functions to verify their correctness. Finally, it introduces the topic of recursion, which will be covered in the next video.

How do you ensure that the decryption process works correctly?

What is the significance of the modulo operation in the shift cipher?

What should happen when you decrypt a string that was previously encrypted?
