How to compare two Python strings for equality in a case-insensitive manner?

# Introduction

When working with text data in Python, you often need to compare strings to determine if they contain the same information, regardless of whether letters are uppercase or lowercase. This is called case-insensitive string comparison.

In this lab, you will learn different methods to compare two Python strings for equality while ignoring case differences. You will explore basic string comparison, various techniques for case-insensitive comparison, and see how to apply these skills in real-world scenarios.

By the end of this lab, you will be able to confidently implement case-insensitive string comparisons in your Python programs, enhancing your ability to handle text data effectively.
