Pi-thon 2022 PSF Spring Fundraiser!!

Launching on a very special day on the calendar, we invite you to honor the PSF and our favorite Greek letter and irrational number with a gift to support the Python ecosystem!

Like Π, our appreciation for the Python community and your support can only be expressed as an approximation—it is greater than words can say. And like our gratitude, Π's digits are infinite. We are sincerely thankful for every single contribution: We couldn't do this without you, and we feel very lucky to share a community with you.

Happy Pi Day!

PS-Don't forget to register for PyCon US! April 27-May 3rd, 2022, in Salt Lake City, Utah and online!
