Introduction Python has an built-in module named Calendar that contains useful classes and functions to support a variety of calendar operations. By default, the Calendar module follows the Gregorian calendar, where Monday is the first day (0) of the week and Sunday is the last day of the week (6). In Python, datetime and time modules also provide low-level calendar-related functionalities. In addition to these modules, the Calendar module provides essential functions related to displaying and manipulating calendars. To print […]

Introduction In this tutorial, we are going to discuss shallow copies vs deep copies with the help of examples in Python. We will cover the definition of a deep and shallow copy, along with its implementation in the Python language to evaluate the core differences between the two types of copies. In many of the programs that we write, no matter how basic they are, we end up needing to copy a list or an object for one of many […]

Introduction The first thing we have to understand while dealing with constraint programming is that the way of thinking is very different from our usual way of thinking when we sit down to write code. Constraint programming is an example of the declarative programming paradigm, as opposed to the usual imperative paradigm that we use most of the time. What is a programming paradigm? A paradigm means “an example” or “a pattern” of something. A programming paradigm is often described […]

Introduction The Python Math Library provides us access to some common math functions and constants in Python, which we can use throughout our code for more complex mathematical computations. The library is a built-in Python module, therefore you don’t have to do any installation to use it. In this article, we will be showing example usage of the Python Math Library’s most commonly used functions and constants. Special Constants The Python Math Library contains two important constants. Pie The first […]
