  Hi there, and welcome to another exciting lesson on JavaScript. If this is your first time here, please do well to check out our previous lessons. In the previous lesson, we were discussing JavaScript math methods. It was very intuitive as we got to learn how to use the various math methods. To proceed, we shall be looking at JavaScript functions.  A function in JavaScript like in every other programming language could be defined as a block of code that is written to perform a particular task, and this function is usually invoked or called before it is being implemented. We have been talking about methods throughout the previous lessons right. Do you know that those methods are actually functions? Yes they are functions. You can now have an overview of the importance of functions in every programming language. How do we create a function in JS? To create a function, you follow the format function functionName(Argument) {//Block of code }. Some functions do have a return val...

Hello everyone, and welcome to another exciting JavaScript lesson. In the last lessons you have been seeing other methods being used in JS (for example, the string methods). We shall go further into exploring other methods. This time, it’s going to be math methods. Do not move an inch because it’s going to be a very exciting. Before we look at what a math method is, let’s have an overview of math objects. A math object in JavaScript is a static built-in object that includes properties and methods used in performing mathematical tasks. Talking about math properties, they have the syntax Math.property . Some examples are Math.E that returns Euler’s number, Math.PI that returns PI, Math.LN2 that returns the natural logarithm of 2, and many others. The various JavaScript methods contained in the math object, thus, make mathematical operations easier and reduce effort as well as time in math-oriented programming. Some JS methods include abs( ), ceil( ), cos( ), sqrt( ), pow( ), log( ) ...

Hello. Welcome to another edition on this platform. For more better understanding, do checkout our YouTube channel to get the video tutorial. In this article of today, we are going to see how to generate random numbers using any of the following methods: Generating a random number Generating a random float and integer Generating random number arrays Generating random number from an array What is a random number? This is a number which cannot be predicted before its occurrence. This number might not different every time. Programmatically, they are two categories of random numbers:     Pseudo-Random numbers       True Random numbers. Just as programs which are written by programmers are a set of instructions, we must follow an algorithm to generate random numbers. Random numbers which are generated using an algorithm are called Pseudo-Random numbers. To generate a true random number, it is important to get the data from sources such as the keyboards, mou...

Hello. Welcome to another session on this platform. If you are new here, please do checkout our previous articles on python programming language and stay excited on this session. we are entering into one of python’s application called Django. In this article, we are going to discuss the following: What is Django Why must we use Django  A brief history of Django Installation of Django Popularity of Django What is Django?

With django, we can launch web applications is a matter of hours. Django is a highly is secured and helps...

Hello. Welcome to another session on this platform. If you are new here, please do checkout our previous articles on python programming language and stay excited on this session because we are entering into one of python’s web-based application called flask. In this article, we are going to see the following What is flask Prequistes Installation of flask in python Some of flask template engine. What is flask? Flask is one of python-based framework which is used to create web applications. Flight is a very light web framework. During installation, flask comes with pre-installed modules and functions which are used to backup your own web applications. Flask is very easy to understand and perfect go-to for beginners and with flask, a web server can run in less than 3 lines of code. Prequistes Before learning flask, we recommend the reader to have a basic mastery of python concepts. Installation of flask  Before installing flask, we have to checked if python has been installed or. If n...

Hello guys. Welcome to another session on this platform. In this article of today we are going look at python OS. For better understanding, do checkout our YouTube channel for the video tutorials. In this article, we are going to discuss the following: What is a python OS module? Some of the different functions under python os module What is a python OS module? We already have a basic knowledge of what a module is. In that light, a python os module provides an easy way for a user to interact with the operating system. This interaction takes place through the use of OS functions. These functions perform os-based task and get some information about the operating system.   We need to import the os module before working with it. import OS Some of the functions in an os module OS.name().  This function returns the name of the operating system as its output Presently it registers the following names of operating system: 'posix', 'nt', 'os2', 'ce', 'java...

Hi guys. Welcome back to another tutorial on python. If you are new here, please do checkout our previous tutorials on python and also do checkout other programming languages.
