Django is a popular web framework used for the development of websites. Django follows the MVT (Model-View-Template) architecture. Here, Model is responsible for the data and logical structure of your project, View contains the business logic and Template is responsible for rendering the HTML files. The hierarchy of project in Django consists of projects and apps. Project refers to the entire web application. Apps are the functionalities that are part of the web application. All of them work individually and can be reused. Creation of a project A project is essentially a collection of settings for a specific instance of ... Read More
In this section, we are going to look at how to install anaconda in your computer. And then we will move into how to install Django in this anaconda environment. Anaconda is a popular run time environment for python programs. The anaconda distribution provides many environments such as Spyder which is an IDLE to run python programs, Jupyter, which is a web application that lets users to perform visualizations and more, and anaconda also includes a PowerShell Prompt that is a command prompt of sorts that lets users to run programs on the command line. Anaconda Installation The steps to ... Read More
A final variable can be explicitly initialized only once. A reference variable declared final can never be reassigned to refer to a different object. However, the data within the object can be changed. So, the state of the object can be changed but not the reference. With variables, the final modifier often is used with static to make the constant a class variable. Therefore, once we declare a final variable it is mandatory to initialize the final variable at the time of declaration or using constructor. If not, a compile time error may occur saying “The blank final field num ... Read More
In this tutorial, we are going to see the Golang program to find the perimeter of a Circle. Perimeter is the total length of the boundary of any closed figure. Formula Perimeter of Circle - 2 * 22 / 7 * r r - radius of a Circle For example, the radius of a Circle is 10 cm so the perimeter of a Circle is − perimeter = 2 * 22 / 7 * 10 = 62.8571428 Finding the perimeter of a circle within the function Algorithm Step 1 − Declaring the variables for ...

In this tutorial, we are going to see the Golang program to find the Area of a Trapezium. The area is the total space covered by any closed figure. Formula Area of Trapezium - ½ * (b1 + b2) * h b1 - length of one parallel side of a Trapezium b2 - length of another parallel side of a Trapezium h - the distance between the parallel sides of a Trapezium. For example, the length of one parallel side of a Trapezium is 10 cm and the other parallel side is 8 cm, and the distance between ... Read More
In this tutorial, we are going to see the Golang program to find the Area of a Parallelogram. The area is the total space covered by any closed figure. Formula Area of the Parallelogram - base * height b - length of the base of a Parallelogram h - length of the height of a Parallelogram For example, the length of the base of a Parallelogram is 6 cm and the length of the height of the parallelogram is 4 cm so the Area of a Parallelogram is − b = 6 cm h = 4 cm Area ...

In this tutorial, we are going to see the Golang program to find the Area of a Square. The area is the total space covered by any closed figure. Formula Area of Square - (length of a side) * (length of a side) s - length of a side of a Square For example, the length of a side of a Square is 10 cm so the Area of a Square is − Area = 10 * 10 = 100 cm^2 Finding the Area of a Square within the function Algorithm Step ...

In this tutorial, we are going to see how to find the number of vowels and consonants in a sentence in Golang. If any character lies under the set {a, e, i, o , u} then that character is a vowel. Any character that does not lie in the above set is a consonant. Explanation Suppose we have a sentence “India have twenty eight states and eight union territories”. In this sentence, the characters which are bold are the vowels. So, the total vowels are 21 and consonants are 29. Finding the count of vowels and consonants within the function ... Read More
In this tutorial, we are going to see how to find the sum of Natural Numbers in Golang. To do that we have two ways one using the formula itself and the other is to use a for loop we will explore both ways in this tutorial. Formula Sum = ( N * ( N + 1))/2 N = The value of the natural number till which you want to find the sum. Explanation Let's find the sum of the first 6 natural numbers using the above formula. Sum of first 6 natural numbers = 1 + 2 + ... Read More
In JavaScript, window.onload and document.ready() are the methods used when the page is being loaded. Window.onload The window.onload method gets executed after the entire web page is loaded. This includes all the elements related with DOM like the head tag, tittle tag and all the other tags including the style sheets, images and videos. The onload method is used by passing a function to it. The called function will be executed after the object is loaded. Syntax This is the syntax of onload method − Window.onload = function() Window.onload = (event) => {} //arrow function Example 1 This example ... Read More
