 <h1>Basic String Operations</h1>
 <p>In this exercise, we’ll explore basic string operations in Python. Strings are one of the most common data types in programming, and Python provides a variety of ways to manipulate them. We’ll practice concatenation (joining strings together), indexing (accessing individual characters), slicing (extracting portions of a string), finding the length of a string, and string repetition.</p>
