WebCython is a hybrid Python/hinted language. In the most basic form it takes the Python code and makes a C file that wraps and calls the Python interpreter. In most cases this has little difference from just running the Python interpreter. WebNumPy provides a C-API to enable users to extend the system and get access to the array object for use in other routines. The best way to truly understand the C-API is to read the source code. If you are unfamiliar with (C) source code, however, this can be a daunting experience at first. Be assured that the task becomes easier with practice ...

WebDec 13, 2024 · Not sure if you can do explicit SIMD stuff, so in that regard one has more optimization opportunities in C/C++. Though, as said, to really get the same performance as C/C++ code, your Cython code has to look very much like C code. So much so, that I’d rather directly write C/C++ code instead, hence my original suggestion.
