Using a computer in order to do rather complex Math is one of the reasons this machine was originally developed. As long as integer numbers and additions, subtractions, and multiplications are exclusively involved in the calculations, everything is fine. As soon as floating point numbers or fractions, as well as divisions, come into play it enormously complicates the whole matter. As a regular user, we are not fully aware of these issues that happen behind the scenes and may end […]

As already pointed out in a previous article titled Commenting Python Code you have learned that documentation is an essential, and a continuous step in the process of software development. The article mentioned above briefly introduced the concept of docstrings which is a way to create documentation for your Python code from within the code. This in-code documentation works for modules, classes, methods, and functions, and it is the preferred way to document all Python code. There is a lot […]

Introduction Memory management is the process of efficiently allocating, de-allocating, and coordinating memory so that all the different processes run smoothly and can optimally access different system resources. Memory management also involves cleaning memory of objects that are no longer being accessed. In Python, the memory manager is responsible for these kinds of tasks by periodically running to clean up, allocate, and manage the memory. Unlike C, Java, and other programming languages, Python manages objects by using reference counting. This […]

Introduction In this tutorial, we are going to learn how to use Python’s PDB module for debugging Python applications. Debugging refers to the process of removing software and hardware errors from a software application. PDB stands for “Python Debugger”, and is a built-in interactive source code debugger with a wide range of features, like pausing a program, viewing variable values at specific instances, changing those values, etc. In this article, we will be covering the most commonly used functionalities of […]

There are a number of different ways to format strings in Python, one of which is done using the % operator, which is known as the string formatting (or interpolation) operator. In this article we’ll show you how to use this operator to construct strings with a template string and variables containing your data. The % Operator This way of working with text has been shipped with Python since the beginning, and it’s also known as C-style formatting, as it […]
