从python GUI使用C编译代码

Question

I am writing an application where I am coding all of my front-end and GUI with python library (wxpython specifically). For this application, I would like to write the model class with C and use python to use the compiled C code? How can this be implemented in python?

I know this is little vague question but I am struggling with the starting point.

Answer 1

If you're using CPython (the most popular version of Python), you'll need to learn the CPython C API . Other python implementations may or may not support C calls. You can also use the ctypes library which is easier to learn, but also more rigid and may not support everything you need.

Answer 2

您可以尝试Cython ，它基本上是Python，具有对C类型和调用的嵌入式支持（通过CPython API进行）。

Answer 3

You could strictly seperate design(python part) and code(c++ part) like this:

Write a complete c++ programm that works in the terminal/console and then make the python-application call these c++-terminal programm via os.Popen.

So if your programm is a calculator it does this:

(python gui) 5 + 5 -> my_c_programm.exe "5 + 5" -> (returns) 10 -> (python gui) display

that way you can use your programm with and without gui.

Its easier and faster than embedding Python in your c++ programm or extending Python with C++.

I basically do the same thing on my current project, but like this:

php: my webinterface python: for structure and logic and easy operation c++: for heavy calculations and where I need speed

so php -> python -> c++

and it works very well for me :)
