Matching Anything and Everything with Regular Expressions in Python

In the world of Python, regular expressions are the unsung heroes. They're like the Swiss Army knives of text processing. But have you ever wondered what kind of wild adventures they could have if they weren't stuck in a programming language?

Imagine a world where regular expressions are not just for matching patterns, but for matching anything and everything. A world where they're not just limited to strings, but also to emotions, thoughts, and even memes.

Let's take a look at some of the most absurd and hilarious examples of matching anything and everything with regular expressions in Python.

Matching Emotions with Regular Expressions

In this example, we'll use regular expressions to match different emotions in a string.

Here's the code:

import re

def match_emotion(string):
    emotions = {
        'happy': r'[:)]+',
        'sad': r'[:(]+',
        'angry': r'[>:]+'
    }
    for emotion, pattern in emotions.items():
        if re.search(pattern, string):
            return emotion
    return 'No emotion detected'

Let's test it out with some examples:

• input: "I am happy to see you!" -> output: "happy"
• input: "I am sad to see you." -> output: "sad"
• input: "I am angry at the state of the world." -> output: "angry"
