Today, we're going to learn how to search and replace within Python strings. These are crucial operations for manipulating text data. This tutorial provides a hands-on approach to implementing these Python features.

Have you ever wondered how to find 'X' on a treasure map, switch code words, or make a search feature to locate a file? By learning how to search and replace text in Python, you can solve these puzzles!

The .find(), .index(), and .count() methods in Python make text searching a breeze.

This method finds the first occurrence of a substring and returns the index. If the substring is not found, it returns -1.

Similarly, rfind() method returns the index of the last occurrence of the provided substring.

This works like find(). However, it throws an error if the substring is not found.

Similarly, rindex() method returns the index of the occurrence of the provided substring.
