If you are confused (like me) that this was about PyPI (Python packages repository) then no. It is about a project called PyPy (one can argue it is bad name) that is an implementation of python interpreter but without cpython. Instead they rely on a JIT compiler. And it is syntax compatible but if your code uses any library or method relying on C extensions then you are out of luck (Goodbye NumPy.. etc). Edit: They have C-layer emulation, but I don't know its limitations or current status, but you can use those libraries [1][2] [1] https://www.pypy.org/posts/2018/09/inside-cpyext-why-emulating-cpython-c-8083064623681286567.html https://www.pypy.org/posts/2018/09/inside-cpyext-why-emulati...

to be fair, PyPy predates PyPI
- miketheman 3y ago
  How so? PyPI launched in 2003, PyPy's first release was in 2007. https://www.pypa.io/en/latest/history/#before-2013 https://www.pypa.io/en/latest/history/#before-2013

    PyPy was started early in 2003 too, the first release took a while. PyPI was branded as 'The Cheeseshop' in the early years.

  Now all we need is a PiPy and we'll have all the pies
  - dpflan 3y ago
    PiPi would complete the set but that would be (doubly) irrational…
    - cdjk 3y ago
      I think you mean transcendental.
      - dpflan 3y ago
        That works too. Perhaps that would be how the pie would taste: truly transcendental, but I don't think it could ever be finished.

THANK YOU. This was my first reaction as well.

They do support numpy. The pypy name predates pypi. You’re off on multiple details here.

Nit. I believe you can use numpy and at least some other libraries relying on native extensions but performance might vary: https://doc.pypy.org/en/latest/faq.html#should-i-install-numpy-or-numpypy https://doc.pypy.org/en/latest/faq.html#should-i-install-num...

> one can argue it is bad name Given the way that pypy is implemented, I think the name is quite clever really.

The packages repo is known as PyPI (like Py P.I.), not PyPi.

PyPy being a Python JIT written in Python with an ouroboros as a logo is pretty much the perfect name.

As a counterbalance, I'm very familiar with PyPy and have never heard "PyPI". > one can argue it is bad name I suppose one can, but it's a python interpreter written in python, so I think it's pretty good.
