Python regex match last word of a string

Title: Python Regex Tutorial: Matching the Last Word of a String
Introduction:
Regular expressions (regex) are powerful tools for pattern matching in strings. In this tutorial, we'll explore how to use Python's re module to match the last word of a string using regular expressions. We'll provide a step-by-step guide along with code examples to illustrate the process.
Step 1: Import the re Module
Before we begin, make sure to import the re module, which provides support for regular expressions in Python.
Step 2: Understand the Regular Expression Pattern
To match the last word of a string, we need to construct a regular expression pattern that identifies a word at the end of the string. Here's a breakdown of the pattern:
The regular expression r'\w+$' can be used to achieve this.
Step 3: Write a Function for Matching the Last Word
Let's create a function called match_last_word that takes a string as input and returns the last word using the regular expression pattern.
Step 4: Test the Function with Examples
Now, let's test our match_last_word function with some examples:
Output:
Conclusion:
In this tutorial, we covered the basics of using Python's re module to match the last word of a string with regular expressions. By following the steps outlined above and using the provided code examples, you can easily integrate this functionality into your Python projects. Regular expressions offer a flexible and efficient way to handle string patterns, making them a valuable tool for text processing tasks.
