Python's REPL (or its interactive shell) has been pretty lacking for a while. Outdated and unintuitive, it proved useful for simple checks, but nothing really that complicated. Thankfully the PSF felt the same, and now Python 3.13 has a new REPL, based on PyPy's! This REPL is massively better than the current one, so I wanted to show it off!

Note: This video uses Python 3.13.0rc1; the REPL is still a little buggy in this version, but I imagine all these bugs will be fixed for the final release.
