Pycon is the flagship conference of the Python community, and has always been one of the highlights of my year. Ticket prices start at just $50 https://us.pycon.org/2021/registration/information/ and the money is invested back into the Python Software Foundation's important work on behalf of Python-lang as well as provides direct support to Python communities around the world and OSS projects such as Beeware, PyPI, and CPython. https://www.python.org/psf/sponsorship-new/#impact
