WebCython is nearly 3x faster than Python in this case. When the maxsize variable is set to 1 million, the Cython code runs in 0.096 seconds while Python takes 0.293 seconds (Cython is also 3x faster). When working with 100 million, Cython takes 10.220 seconds compared to 37.173 with Python. WebThis file is a Python file that executes the Cython compilation. Its purpose is to generate the compiled .pyd file that may then be imported by Python modules. In this example, we have kept all the required files (i.e. complexFunLib.h, complexFunLib.dll, ccomplexFunLib.pxd, and complexFunLib.pyx) in the same directory as setup.py.
