When compiling against Python 2 this means faking up the Python 3 API and when compiling against Python 3 faking the old Python 2 API. ) So that’s saying something, I think. Well, there is an experimental Python -> C++ compiler described here:. cpp extension. Create a C++ extension for Python. txt, which is included with the pyodbc distribution). Integrate compiled MATLAB ® functions into Python ® applications. Emscripten compiles LLVM bitcode into JavaScript, which makes it possible to compile C and C++ source code to JavaScript (by first compiling it into LLVM bitcode using Clang), which can be run on the web. Cython works by first translating Python code into equivalent C code that runs the Python interpreted through the Python C API. Many open-source projects, including the GNU tools and the Linux kernel, are compiled with GCC. 7 via /usr/bin/python3. Now spelled GnuCOBOL, 2. py build_ext --inplace.

The initial compilation provides some speed increases (by bypassing the CPython interpreter layer), and Cython’s optional static typing features can offer additional opportunities for speed increases. The darker the yellow, the more idiomatic Python, and the more lines of C behind it. Such extension modules can do two things that can’t be done directly in Python: they can implement new built-in object types, and they can call C library functions and system calls. The Nim compiler and tools are all written in Nim and licensed under the MIT license, with most development taking place on GitHub.
