Python Tutorial 2.1.5 - Using the String Method 'Casefold' 'Upper' 'Lower'

In this tutorial, we will be exploring three Python string methods: "casefold", "upper", and "lower". These methods allow you to manipulate the case of a string, making it all lowercase or uppercase, or even changing the case of specific characters while leaving others unchanged.

We'll start with some simple examples to demonstrate the basic syntax of each method, and then move on to more advanced examples to show how you can use them in more complex situations.

Throughout the tutorial, we'll be using Python 3.x syntax, and assuming that you have some basic familiarity with Python programming concepts. By the end of the video, you should have a solid understanding of how to use these methods to manipulate the case of strings in your Python programs.
