Most programming languages have a module to deal with randomness. Python is no exception coming with the module named random and in this article, we’ll be looking at the most essential functions you need to use it. The Absolute Basics Before we use any function from the random module, we must import it. import random Because we’re dealing…

For example, the ServiceLoader is used by SLF4J: one adds the slf4j-api on the classpath at compilation time, while any single impl

Building a Python C Extension Module

There are several ways in which you can extend the functionality of Python. One of these is to write your Python module in C or C++. This process can lead to improved performance and better access to C library functions and system calls. In this tutorial, you’ll discover how to use the Python API to write Python C extension modules. You’ll learn how to: Invoke C functions from within Python Pass arguments from Python to C and parse them accordingly Raise exceptions from C code and create custom Python exceptions…
