In this tutorial, you’ll learn how to use the index() method in Python to find the position of a character or substring within a string. The index() method is similar to find(), but with a key difference: it raises an error if the substring is not found—making it ideal when you expect the value to exist.

We'll explore how index() works, how to use it with optional start and end parameters, and compare it with the find() method through real-world examples.

🔹 What you'll learn:
