2 days ago · It is quite easy to add new built-in modules to Python, if you know how to program in C. 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.

Jul 1, 2013 · Like Gene recommended, the best way is to look at the sources and find out which module are implemented in C. You can check the __file__ module's attribute : In this example, it's a .so file which has been loaded, therefore this module is implemented in a compiled language (most probably in C). Does python use any other compiled (to .so) languages?

Jul 15, 2018 · cPython has two main ways to call C code: either by loading a shared library and calling its symbols, or by packing C code as Python binary modules and then calling them from Python code as though they were ordinary Python modules, which is how high performance stuff in the standard library is implemented - e.g. json.

Sep 22, 2021 · But I can't find others like for example the sys module, which I believe is written in C. Where can I find that? You can find the C source code on the CPython GitHub: https://github.com/python/cpython. The sys module is here, specifically: https://github.com/python/cpython/blob/main/Python/sysmodule.c

Jan 20, 2011 · The rawest, simplest way is to use the Python C API and write a wrapper for your C library which can be called from Python. This ties your module to CPython. The second way is to use ctypes which is an FFI for Python that allows you to load and call functions in C libraries directly. In theory, this should work across Python implementations.

A module is a file with the extension .py and contains executable Python or C code. A module contains several Python statements and expressions. We can use pre-defined variables, functions, and classes with the help of modules.

Aug 3, 2012 · From Python, we’re going to call the function with the command _chi2.chi2 where _chi2 is the name of the module and chi2 is the name of the function.

Mar 27, 2019 · Writing a simple C extension module directly using Python’s extension API and no other tools. It is straightforward to make a handcrafted extension module for a simple C code. But first, we have to make sure that the C code has a proper header file.

Jul 3, 2020 · Python modules can be written in pure Python but they can also be written in the C language. The following shows how to extend Python with C. Using the Python/C API

Dec 16, 2023 · Well, the answer is both C and C++. Yes, you read it right! Python’s implementation is written in a combination of these two powerful languages. Guido van Rossum, the creator of Python,...
