PyPy: The FASTEST Python implementation

"If you want your code to run faster, you should probably just use PyPy."

I mean, who can argue with the big boss?

The fact that it runs numpy slower than CPython makes it not very useful. I can't imagine any scenario where your python program is so computationally expensive that you need a faster alternative, but you don't already use numpy.

Pandas not working with pypy is there any other solutions please help me.

The reason it can cast string to array<int8>[] and char to int8 is because a string is just an array of int8 values.

Any thoughts on using pyscript instead of javascript? I understand it's known to be much slower but perhaps techniques/updates have changed recently where the performance hit isn't so bad?

Hi im trying to use PyPy as interpreter in jupyter notebook but I cannot install packages using "pip install package_name" or "pypy -m install package_name". Can u suggest a solution

the fastest? i wouldnt be so sure about that. Nuitka can be really fast in some cases, Taichi/Numba are technically implementations of python, which JIT compile it, Cython compiles type-annotated python to C, MyPyC also compiles mypy-checked python... and almost all of them are in some ways faster than PyPy.

Tried to use this but literally can't pass in arguements into the pypy files, which means they're shipping their binaries completely broken

"The FASTEST Python implementation"
Graal Python or GraalPy would disagree. GraalVM provides a Python 3.8 compliant runtime. The aim is to bring compatibility up to python 3.10.
