Apr 22, 2011 · Next, as to your actual question, there are certainly advantages of using the Python/C API directly: Most likely, you are more familar with writing C code than writing Cython code. Writing your code in C gives you maximum control. To get the same performance from Cython code as from equivalent C code, you'll have to be very careful.
Sep 15, 2018 · Nowadays, three modern tools are widely used in the Python community that support manual wrapping: Cython, cffi and pybind11. These three tools serve three different sides of the need to extend (C)Python with native code. Cython is Python with native C/C++ data types. Cython is a static Python compiler.

Talking about CPython, it is the default implementation of Python specifications. It comes with the python distribution itself and interprets the python programs for the machine. Given that it is the default implementation of Python, whenever Python is upgraded with new features, language developers upgrade the CPython version as well and include i...
Cython is a separate compiler that can understand both Python and C specifications. It is more like a superset of Python compiler and allows you to work with Python and C together in a single project. How does this help? Alright, so, Cython compiles the hybrid python and C code into a very efficient C program which in turn can be compiled to the ma...
PyPy works on the Just in Timecompilation principle. Like interpreters, JIT compilers also pick up the raw code but turns the code into efficient machine code just before the execution. There are a lot of optimization techniques involved in JIT compilers and that makes JIT compilers work much faster than the raw interpreters. PyPy also consumes les...
While there are multiple compilers, they all try to solve different problems and work differently. Looking at the statistics and usage, Cython seems to be the leader in the game and provides the fastest execution speeds, has a great community, good documentation, and is a potential candidate to get included in the default python distribution itself...
Aug 6, 2023 · C, on the other hand, is faster and can interact with hardware, but has a steep learning curve. Cython, a superset of Python, bridges the gap between Python and C or C++. Its aim is to make writing C extensions for Python as easy as Python itself. The rationale is that the C extensions can perform much more quickly as stand-alone modules than ...
In scikit-learn, we have decided early on to do Cython, rather than C or C++. That decision has been a clear win because the code is way more maintainable. We have had to convince new contributors that Cython was better for them, but the readability of the code, and the capacity to support multiple Python versions, was worth it.« → Gaël ...
Dec 19, 2022 · Python 3.11 can be twice as fast compared to older versions of Python. Still, there is a large gap to the performance of C++, which is about 17 times faster. These results are valid only for the ...

Jun 11, 2023 · Cython Time: 0.0028510200. Cython was 139.280 times faster. Cython is also just alot better at handling recursion than Python, which is why we see such a big performance boost. Doing this on the non-recursion version will not yield such a large difference, as we will see in the next benchmark.
