Depending on your computer/setup there are many options but [Python Release Python 3.15.0rc3 | Python.org](https://www.python.org/downloads/release/python-3150rc3/)

If you have [uv](https://github.com/astral-sh/uv):

```python
uv python install 3.15rc3

```

Make sure `uv` is up-to-date.

A vote for pyenv instead of uv here! Just started using it yesterday to install the latest python due to older system python on Debian and it was a breeze. I don’t know if it has that particular one but it did list loads of them and installing specific versions is a snap. Very straightforward to start using it as well, as I was up and running in an hour or two.
