I visited the PyCon website the other day, but could find no obvious list of upcoming US PyCons beyond 2027 in Long Beach. Is that how far in advance US locations have been set?
I think pycon.org is missing a lot of the regional ones, but I found them on the wiki:
PythonConferences
Several of the regional US ones are still upcoming this year. PyOhio and PyBeach are both coming soon.
I didn’t poke through all of them, but I’d start from that listing if you’re looking for a US con other than the main annual one.
