In the superfastcode project, the 7 | module is exposed to Python using the extension methods for CPython. In the superfastcode2 project, the module is exposed using PyBind11. 8 | 9 | The CppAndPython project contains a little Python code that implements the same function using straight Python, then runs all three implementations 10 | to provide comparative results. Note that you may need to update the selected environment under the **Python Environments** node. The sample was 11 | written for Python 3.6 (32-bit). Make sure a suitable environment is selected here. 12 | 13 | Because the superfastcode and superfastcode2 C++ projects contain a few hard-coded pathnames and is also configured to compile using the Visual Studio 2017 14 | toolset, you may need to change a few project properties as described in the table below to make them work on your computer.
