It seems like you’re referring to “Pythex,” which is a commonly used online tool for testing and experimenting with regular expressions in Python.

Regular expressions are a powerful way to search, match, and manipulate text patterns. Pythex allows you to input a regular expression and test it against sample text to see how it matches or extracts certain patterns.

If you want to use Pythex, you can visit the website https://pythex.org/ and start experimenting with your regular expressions and sample text right away.
