Using regex to find and replace phone number extensions Python

Regular expressions (regex) are a powerful tool for pattern matching and manipulation of text. In this tutorial, we'll explore how to use Python's re module to find and replace phone number extensions within a text using regular expressions. Phone number extensions are typically numeric sequences that come after the main phone number, often separated by characters like hyphens or spaces.
We'll cover the following topics:
Let's get started!
First, you need to import the re module, which provides functions and classes for working with regular expressions.
To match phone number extensions, we need to create a regex pattern. Extensions typically consist of one or more digits, and they may be preceded by characters like hyphens, spaces, or periods. We can use character classes and quantifiers to create a pattern that matches these variations.
Here's a regex pattern that matches phone number extensions:
This code will replace any phone number extensions in the text with "[EXTENSION]" and print the modified text.
That's it! You've learned how to use regex to find and replace phone number extensions in Python. You can adapt these techniques to various scenarios where you need to manipulate text containing phone numbers and extensions.
Remember that regex patterns can be adjusted to match different formats or patterns depending on your specific requirements.
