Video Overview
In this lecture we explore string manipulation in Python with a practical example. You will learn how to access and modify characters within strings using indexing starting with simple tasks like printing specific characters from the alphabet. We then move on to something exciting implementing a Caesar Cipher. This classic encryption method shows how to shift letters and encrypt messages while using the modulo operator to prevent errors. By the end of this lecture you will understand how to play with strings and unlock interesting coding possibilities in Python.
