Pygame is a popular Python library used for building games and multimedia applications. One of the most important aspects of game development is the ability to create scrolling backgrounds. In this article, we will cover the essential steps for creating a scrolling background in Pygame. We will also provide real-world examples and code snippets to help you understand the concepts better. Other libraries which can also be used for game development in python − Arcade − Arcade is a modern, easy-to-use library for creating 2D arcade-style games. It is designed to be easy to learn and use, and provides ... Read More

Bokeh is a powerful data visualization library in Python that helps to create interactive and unique visualizations for the web. Bokeh supports various rendering techniques and provides a wide range of built-in tools for creating complex visualizations with multiple glyphs. This document will guide you through the process of creating a plot with multiple glyphs using Bokeh. This plot combines different glyphs to display multiple data series in a single plot that provides a more efficient way to understand the relationship between different variables. What are Glyphs and what are the key advantages of these? Glyphs are graphical representations ... Read More

A Pandas DataFrame is a two-dimensional table with rows and columns that are immutable, meaning they cannot be changed once they are created. Creating a DataFrame from scratch with lists is a common task in data science and information technology. A list is an ordered collection of elements, and it is one of the most commonly used data structures in Python. A list can store any type of values such as numbers, strings and boolean values. In this document, I will provide a detailed explanation of how to create Pandas DataFrame from lists with real-world examples using step-by-step instructions, code ... Read More

In today's data-driven world, having efficient ways to handle data is essential, and SQLite is one of the best solutions for small-scale database systems. SQLite is a popular relational database system, that is easy to use, lightweight, and scalable. One way to store data in SQLite, is to store it in CSV format. This allows us to store structured data in flat files, which can be easily parsed with the help of Python. In this tutorial, we will learn how to create a SQLite database from CSV files, using Python. What is a SQLite Database? SQLite is a software library ... Read More

A Vehicle Identification Number (VIN) is a unique 17-digit code assigned to every vehicle manufactured after 1981. It contains information about the vehicle’s make, model, year of manufacture, country of origin, and other relevant details. In this instruction manual, we will learn how to create a Graphical User Interface (GUI) using Python programming language to extract vehicle information from a VIN number. Prerequisites Before we dive into the details of creating a GUI, you should have a basic understanding of Python programming, object-oriented programming (OOP) concepts, and how to work with the Tkinter module. List of recommended settings pip ... Read More

In Haskell we can check whether a given number is Armstrong or not using list comprehension and sum function. Armstrong numbers, also known as narcissistic numbers, are numbers such that the sum of the cubes of their digits is equal to the number itself. For example, the number 153 is an Armstrong number because 1^3 + 5^3 + 3^3 = 153. Algorithm Step 1 − The armstrong function calculates the sum of the cubes of the digits of n using list comprehension and the sum function, and define Step 2 − Program execution will be started from main function. ...

In Haskell, we can check whether a given year is a leap year is not using simple boolean expression. A leap year is a year that has an extra day (February 29th) compared to a normal year. For example, 2004 is a leap year. To determine if a year is a leap year or not, there are a few rules that must be followed. Algorithm Step 1 − The isLeapYear function is defined Step 2 − Program execution will be started from main function. The main() function has whole control of the program. It is written as main ...

In Haskell, we will convert Array to Set (HashSet) by using fromList, nub and foldr functions. In the first example, we are going to use ( let set = Set.fromList arr) and in the second example, we are going to use ( let set = nub arr). And in the third example, we are going to use (let set = foldr Set.insert Set.empty arr). Algorithm Step 1 − The Data.Set module is imported to work over set. Step 2 − The program execution will be started from main function. The main() function has whole control of the ... Read More

In Haskell, we will convert File to byte array by using B.readFile function along with fromIntegral and foldl function. In the first example, we are going to use ( let byteArray = B.unpack bytes) and in the second example, we are going to use (let wordArray = map fromIntegral (B.unpack bytes) :: [Word8]). And in the third example, we are going to use (let byteArray = B.foldl' (\acc byte -> acc ++ [byte]) [] bytes). Algorithm Step 1 − The Data.ByteString modules are imported. Step 2 − The program execution will be started from main function. The main() ... Read More
