Later we will be animating our flag with wave animation and flag movement. These are the steps which we will be following: .flag-container { ...
Read MorePython program to get first and last elements from a tuple
Tuples are an important data type in Python and are often used to store a fixed set of elements. In this article, we will be discussing how to extract the first and last elements from a tuple in Python. We will go over the syntax for accessing these elements and will provide examples of how to do so. What is a Tuple in Python? Tuples allow for the storage of several things in a single variable.

Read MoreHow to Package and Deploy CLI Applications With Python
Based on the interface we have two types of applications CLI (Command Line Interface) applications and GUI (Graphical User Interface) applications. A command line application or, console application is the one which can be accessed from a shell or, command line through a text interface, these accepts inputs from the user in the text format. Unlike GUI Applications which provides a Graphical interface containing, buttons text boxes and icons, to the users to access the underlying application. Python is a popular programming language for developing CLI applications, though the process of packaging and distributing such applications is a bit ...
Read MoreCommand Line File Downloader in Python
Python is a powerful programming language that provides many tools and libraries for different applications. We can also create a command line file downloader in python. Command line downloader is used to download files from internet manually through command line interface or your terminal without using browser. To create a command line file downloader in python we need two libraries, they are argparse and required. We should have basic knowledge of terminal or command line interface and python language before we start building this application. Installation Before we continue, we need to have the above mentioned libraries in our ...
Read MoreConnect new point to the previous point on a image with a straight line in OpenCV-Python
We might have to draw lines on an image for various purposes like drawing, scribbling, tracking the movements of a point etc. so it is necessary to know how to connect 2 points in image processing. OpenCV is a library of programming functions primarily for real-time computer vision. The library is cross-platform and licensed as free and open source software under the Apache License. In this article, we will learn how we can connect a new point to the previous point on an image with a straight line using OpenCV-Python. Connecting a Points on with the Previous One ...
Read MoreConvert BGR and RGB with Python and OpenCV
OpenCV is a library of programming functions primarily for real-time computer vision. The library is cross-platform and licensed as free and open source software under the Apache License. It is written in C++ and has Python bindings that make it easy to use in Python applications. In this article we are going to learn how to Convert BGR and RGB with python and OpenCV. Before proceeding further first of all let us understand BGR and RGB. What are BGR and RGB RGB and BGR are both color models used to represent colors in digital images. However, the main difference between ...
Read MoreHow to Package a Command Line Python Script
Python is a powerful programming language that has various applications in the world of software engineering and is very widely used. We can create various types of applications using Python. We can also make a CLI script in Python which can be used to automate many tasks. We can also then package the CLI scipt. For these scripts to be used by other we need to package and distribute these applications. So we must know how we can package a command line python script.

Read MoreCommand Line Scripts - Python Packaging
Python is a very popular and powerful programming language which is used to create a large number of applications with different purpose. A command line interface script or CLI script is a script that performs a specific task which is scripted, when it is executed through command line and it is used to automate so many tasks. A CLI script is very useful for developers. We can also create these CLI scripts in python. After creating a CLI script we can also package it and share it with other programmers to use. Therefore, we must know how to package ...
Read MorePython Program to sort a tuple of custom objects by properties
Let us now dive into what a custom object in python is. We know that python provides us with a lot of pre-defined datatypes which can be used to store various types of data. But there are times where we have to define custom datatypes that can store data that cannot be represented by built-in datatypes. For this purpose, python provides us “classes”, these classes help us customize and create that is fit for our needs. A class can have data and function to implement some behavior. An example of implementing a class in python is as follows − class ...
