How to Properly Include Single Quotes in Words with Regex in Python

When working with strings in Python, you might encounter the challenge of extracting words while preserving contractions, such as "won't." If you've tried using regex to accomplish this, you may have found that the default patterns often break down these terms into separate words, which is not what you want. In this post, we'll explore how to ensure your regex captures entire words, including those with single quotes.

The Problem: Capturing Words with Contractions

Consider the example string:

Using a basic regex pattern might yield an output like this:

What you truly want is the output:

The challenge here is to make sure that the regex accounts for words that contain apostrophes, allowing us to keep contractions intact.

The Solution: Adjusting Your Regex Pattern

To resolve the issue with capturing words correctly, you'll need to modify your regex pattern. Instead of the initial approach that may have looked something like this:

Here’s the updated version that solves the problem:

Explanation of the Regex Pattern

\w - This matches any word character, which includes letters (both lowercase and uppercase), digits, and underscores.

' - By including the single quote ' character in the brackets, we explicitly tell our regex to consider it as part of a word. This means that contractions like "won't" will be treated as a single word rather than two separate entities.

Breakdown of the Code:

Import the Regex Library:
Start by importing the re module, which is essential for regex operations in Python.

Define Your String:
Set up the string you want to analyze with contractions.

Applying Regex:
Use re.findall() with the new regex pattern to extract words while preserving contractions.

Print the Output:
Display the resulting list of words to verify that it includes "won't" as intended.

Conclusion

By adjusting your regex pattern to account for single quotes in words, you can effectively extract the full terms you need, even when contractions are present. This approach will not only simplify your string processing tasks but also enhance the accuracy of your data extraction efforts.
