Regular expression to return text between parenthesis

Tech Blog: Unleashing the Magic of Regular Expressions 🎩✨

👋 Hey there tech enthusiasts! Today, we're diving into the world of regular expressions, unlocking a secret technique that will empower you to retrieve text between parentheses in an instant. Whether you're a beginner or a seasoned coder, this guide will equip you with the knowledge and tools you need to conquer this common challenge. Let's get started! 🚀

The Challenge: Extracting Text between Parentheses

🧩 Imagine you have a string that looks like this:

u'abcde(date=\'2/xc2/xb2\',time=\'/case/test.png\')'

🔍 Your mission is to extract the contents within the parentheses and return it. In this case, we want to extract:

date='2/xc2/xb2',time='/case/test.png'

The Superpower: Regular Expressions

⚡ Regular expressions, or regex, are a powerful tool for finding and manipulating text. With a bit of regex magic, you can easily solve this challenge.

❗ Before we proceed, let's clarify that different programming languages might have slightly different regex syntax, but the core principles we'll discuss here remain the same.

The Solution: Mastering Regular Expressions

✏️ To extract the text between parentheses, we can use the following regex expression:

\((.*?)\)

🔎 Now let's break it down:

• \(: Matches the opening parenthesis "("

• (.*?): Matches any character (represented by "."), zero or more times (represented by "*?"), in a non-greedy manner (to capture the smallest possible match)

• \) : Matches the closing parenthesis ")"

Putting it together, this expression allows us to extract the desired text between the parentheses.

Python Implementation: Code Like a Ninja 🐍👤

💻 Here's an example of how you can use this regex expression in Python:

import re

input_string = u'abcde(date=\'2/xc2/xb2\',time=\'/case/test.png\')'
matches = re.findall(r'\((.*?)\)', input_string)

if matches:
    extracted_text = matches[0]
    print(extracted_text)

🎉 Running this code will yield the following output:

date='2/xc2/xb2',time='/case/test.png'
