## Summary In Python 3.13, at least in the current builds, there's no `python.exe`, but there is `venvlauncher.exe`. I've asked here about whether it's intended: https://discuss.python.org/t/when-should-venv-scripts-nt-python-exe-be-present/47620. But there's at least some evidence in CPython [here](https://github.com/python/cpython/blob/d457345bbc6414db0443819290b04a9a4333313d/Lib/venv/__init__.py#L270) that we should fall back to these, and the tests pass. Closes https://github.com/astral-sh/uv/issues/1636.
