PyPy: Python in Python Implementation

Welcome to PyPy!

PyPy is an interpreter that implements the Python programming language, based on the RPython compiler framework for dynamic language implementations.

The home page for the interpreter is:

https://pypy.org/

If you want to help developing PyPy, this documentation might help you:

https://doc.pypy.org/

More documentation about the RPython framework can be found here:

https://rpython.readthedocs.io/

The source for the documentation is in the pypy/doc directory.

Using PyPy instead of CPython

Please read the information at https://pypy.org/ to find the correct way to download and use PyPy as an alternative to CPython.

Building

Building PyPy is not the recommended way to obtain the PyPy alternative python interpreter. It is time-consuming and requires significant computing resources. More information can be found here:

https://doc.pypy.org/en/latest/build.html

Enjoy and send us feedback!

Using pypy sandbox for indie game for scripting game assets

I'm looking for a secure and relatively performant environment to run python scripts that influence the game mechanics of my game. The user should be able to mod the game and create python scripts along with other game assets and be able to upload these assets to a server where others can download it. Needless to say these scripts should be run in a contained environment to not cause harm for the unsuspecting end user.

I was led here by this and thought I might look into it. My setup is a bit different that the game will be written in C++ and have pyhton c API bindings for the game API.

As I get from the wiki the sandbox is currently deprecated and a new one is in development progress. I have now two questions:

1. Is pypy sandbox suitable for my use case?
2. How is develpment coming along? Can the new sandbox be reliably used alredy?

I like the intricacies of the pypy sandbox as opposed to the not really viable alternatives. Maybe someone knows more as well, I'm open.

Sorry for opening an issue here but I didn't find a discussion thread :)

how is this being mirrored?

I am a PyPy dev, and am considering how we can use some of the nice CI providers available to github projects but not available to other code hosting sites like foss.heptapod.net

I am curious how you are mirroring this. Is there a machine running a cron job somewhere? Would it be reasonable to mirror via a github actions cron task?

PyPy --version doesn't print into standard output

Command:
pypy --version >> pypy.version

will not output to file, while command:
pypy --version >> pypy.version 2>&1

will. Which points out, it's probably not in standard output, but 'File descriptor 2 is the standard error (stderr).' (https://stackoverflow.com/questions/818255/in-the-shell-what-does-21-mean)

how I found it:

Ensuring pip modules work smoothly post pypy installation (after trying ensurepip option)

Im using anaconda's pip as a command line default and have quite a lot of packages already. I just want to make sure the pypy installation done using pip can access these same modules without reinstallations. Is there a quick and easy way?
I tried this way (https://docs.python.org/3/library/ensurepip.html) and Im unable to provide the default pip if I try
./pypy3-c -m ensurepip --default-pip "~/anaconda/bin/pip"

python -m ensurepip: error: unrecognized arguments: ~/anaconda/bin/pip

Sad to say couldn't find a solution to install opencv for pypy3 on windows 10

Even finding the whole web didn't a way to install opencv through pip or local install it always fails
Please we need opencv and numpy for pypy

the two results are completely different.

Broken links in docs.

The links under the "Layers" RPython subsection are all broken in some way.

The first, :ref:RPython <rpython:language>, points to https://github.com/mozillazg/pypy/blob/master/pypy/doc/architecture.rst#id15, which is just the same page.

The second, Getting Started with RPython, points to, which leads to a "Sorry This page does not exist yet".

The third, RPython By Example, points to https://mesapy.org/rpython-by-example/, which 404s

possible version mismatch

I am running into a problem with running NURBS-Python and the NURBS-Python_Examples when running with pypy3 returning "ImportError: cannot import name 'ft2font'" and similar errors. My only guess at this point is that Python-3.7 is installed on the system, and pypy appears to be built against 3.6 -- see version info:

Python 3.6.9 (?, Apr 10 2020, 19:47:05)
[PyPy 7.3.1 with GCC 7.3.0]

As far as I can tell it appears to be an issue with the versioning. All tests were passing in version 3.4/5.

Please let me know when you bump to python-3.7 and 3.8 so I can test them against my systems.

Potential Bug in collections.Counter

Abstract:
pypy returns False for

Counter(a=4, b=2, c=0) == Counter(a=4, b=2)

Hi, while writing a simple code, I found a potential bug from Counter class.
As written in abstract, pypy returns False for Counter(a=4, b=2, c=0) == Counter(a=4, b=2),
while Python3 returns True for the same.

The reason seems to be the absence of __eq__ method in pypy's Counter class, while cpython's Counter class has.

Considering the characteristics of the Counter class, returning True to the upper statement seems to be more reasonable. Maybe pypy should add __eq__ statement too.

runing following code in pypy 7.3.12 is 3 times slower than in python 3.8
