Thank you for your PR! Can you please rebase it? I had to revert to ubuntu-20.04 in the github actions to make the build work.

Yup, and there is also an f-string. Maybe we'll drop support for Python 2 in the next major version.

The tests are ok. Could you please add an example of regex matching in the readme file, so users know how to use your feature? Thanks!
