    1 project | /r/learnpython | 12 Jun 2023
    The approach that I favour is to use Cython. The nice thing with this approach is that your code is still written as (almost) Python, but so long as you define all required types correctly it will automatically create the C extension for you. Early versions of Cython required using Cython specific typing (Python didn't have type hints when Cython was created), but it can now use Python's type hints.

    Just for reference,

    * Nuitka[0] "is a Python compiler written in Python. It's fully compatible with Python 2.6, 2.7, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, and 3.11."

    * Pypy[1] "is a replacement for CPython" with builtin optimizations such as on the fly JIT compiles.

    * Cython[2] "is an optimising static compiler for both the Python programming language and the extended Cython programming language... makes writing C extensions for Python as easy as Python itself."

    * Numba[3] "is an open source JIT compiler that translates a subset of Python and NumPy code into fast machine code."

    * Pyston[4] "is a performance-optimizing JIT for Python, and is drop-in compatible with ... CPython 3.8.12"

    Profile and optimize the hotspots with cython (or whatever the cool kids are using these days... It's been a while.)
  • What exactly is 'JIT'?
    1 project | /r/ProgrammingLanguages | 10 Apr 2023
    JIT essentially means generating machine code for the language on the fly, either during loading of the interpreter (method JIT), or by profiling and optimizing hotspots (tracing JIT). The language itself can be statically or dynamically typed. You could also compile a dynamic language ahead of time, for example, cython.

    No.

    …and this one is no exception -> https://github.com/RustPython/RustPython/issues/1940

    Packages that rely on c dependencies like numpy, etc. only work if you write a custom implementation by hand; the “normal” package flat out doesn’t (and cannot) work.

    If you absolutely need something comparable to Sympy, then one option might be to figure out how to best call Sympy from Rust. e.g. - RustPython, although it seems like Sympy isn't supported yet - Pyodide, and figuring out how to run it outside of a web browser. Probably also not very easy. - PyPy, and having a pretty simple Python binary for every platform - ...
