   Nov 4, 2014 · It doesn't, really: Cython is a Python-like programming language to write C extension modules for Python (the Cython code gets translated into C, together with the necessary C-API boilerplate). It provides some basic C++ support.

   Jul 29, 2020 · Python utilizes a system, which is known as "Call by Object Reference" or "Call by assignment". If you pass arguments like whole numbers, strings, or tuples to a function, the passing is like a call-by-value because you can not change the value of the immutable objects being passed to the function.

   • A Simple Example¶ Let’s create an extension module called spam (the favorite food of Monty Python fans…) and let’s say we want to create a Python interface to the C library function system() [1].
   • Intermezzo: Errors and Exceptions¶ An important convention throughout the Python interpreter is the following: when a function fails, it should set an exception condition and return an error value (usually -1 or a NULL pointer).
   • Back to the Example¶ Going back to our example function, you should now be able to understand this statement: if (!PyArg_ParseTuple(args, "s", &command)) return NULL;
   • The Module’s Method Table and Initialization Function¶ I promised to show how spam_system() is called from Python programs. First, we need to list its name and address in a “method table”

   Mar 18, 2019 · Prerequisite: How to Call a C function in Python. Let’s discuss the problem of accessing C code from Python. As it is very evident that many of Python’s built-in libraries are written in C. So, to access C is a very important part of making Python talk to existing libraries.

   Can I call C code from Python?

   • The goal is to call C code from Python. You should be able to do so without learning a 3rd language: every alternative requires you to learn their own language (Cython, SWIG) or API (ctypes). So we tried to assume that you know Python and C and minimize the extra bits of API that you need to learn.

   Is it possible to invoke C function or executables in Python?

   • I want to invoke those C function or executables in python. Is that possible. Yes, you can write C code that can be imported into Python as a module. Python calls these extension modules. You can invoke it from Python directly, an example from the documentation: Python Code C Code // do something return Py_BuildValue("i", result);

   Can you call Python interpreter in C code?

   • I know that Python provides an API so you can call Python interpreter in C code, but what I want is the opposite. My program needs to use some C API, so the code must be written in C. But I also want to package the program with Python. Which means I want to invoke those C function or executables in Python. Is that possible?

   How do I call a python function?

   • Calling a Python function is easy. First, the Python program must somehow pass you the Python function object. You should provide a function (or some other interface) to do this. When this function is called, save a pointer to the Python function object (be careful to Py_INCREF() it!) in a global variable — or wherever you see fit.

   Is Cython a good programming language?

   • Cython offers a blend of Python’s ease and C’s performance, allowing you to write Python code that compiles to C. It requires learning some Cython-specific syntax but is highly efficient for optimizing performance-critical sections of code.

   How do you communicate between Python and C?

   • Most communication between a Python and C process revolves around passing structs back and forth, either over a socket or through shared memory. I recommend creating a Command struct with fields and codes to represent commands and their arguments.
