Hello pupil! We hope you are doing well with object-oriented programming with Python. OOP is an extremely important topic in programming, and the good thing about Python is that the concept of OOP can be implemented in it. In the previous lecture, we made a basic introduction to all the elements that are used in the OOP, and right now, we are moving forward with the detail of each concert with examples. The imperative nature of the OOP is useful for us because it uses the statements to change the programming state, and in this way, the working of the code becomes easy and effective. To use the applications of Python, the imperative nature of OOP will give us the tools we need to get the perfect results by using our creativity. We will prove this in just a bit, but here are the highlights o ...
Hey, learners! Welcome to the next tutorial on Python with examples. We have been working with the collection of elements in different ways, and in the previous lecture, the topic was the built-in functions that were used with the sets in different ways. In the present lecture, we will pay heed to the basic operations of the set and their working in particular ways. We are making sure that each and every example is taken simply and easily, but the explanation is so clear that every user understands the concept and, at the same time, learns a new concept without any difficulty. The discussion will start after this short introduction of topics:
How do we declare and then find the difference between the two sets?
What are the built-in functions for operations, and how do we use them in the ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at Properties in C#. It's our 20th tutorial in C# Series and a quite important one as we are gonna use properties a lot in our coming lectures.
If you haven't studied C# Methods & C# Classes then I would suggest you to read them first before starting today's tutorial, as we are gonna use methods today. So, let's get started with Properties in C#:
Introduction to Properties in C#
Today I am not gonna start with the definition as I did in previous tutorial, instead we will first understand the concept and then will define it.
So, let's create a new C# Class named StudentsClass shown in figure on right side.

Hello everyone, I hope you all are fine and having fun with your lives. Today, we are going to design our First Project in C#. In the previous tutorial, we have seen a detailed Introduction to C#, where we have studied its importance in the software world.
Today, we are going to create our first project in C#. So, let's get started with our first code in the C# Tutorial series.
First Project in C#
I am going to use Microsoft Visual Studio 2019 Community Edition, which is free to use, and you can download it from its official website.
There are different languages available in Visual Studio i.e. C, C++, C# and F#. C# is the most commonly used programming language among all.
Now, I assume that you ha ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to use Environment Variables in ASP.NET Core. It's our 5th tutorial in ASP.NET Core series. In our Startup.cs file, you must have seen that we have an IF Condition at the start and this IF Condition has IsDevelopment in it.
This condition is actually checking the environment of our web application. So, here we will first discuss them and then will see why we need them. So, let's get started:
Environment Variables in ASP.NET Core
ASP.NET Core has 3 builtin Environments, which decides the Run-time operating environment of the web application, which are:
Development.
Staging.
Production.
In order to set this Environment Variable, we need to ...
Hello Python programmers! Welcome to the engineering projects where you will find the best learning data in a precise way. We are dealing with Python nowadays, and today, the topic of discussion is the arrays in the language. We have seen different data types in Python and discussed a lot about them in detail till now. In the previous lecture, we saw the details of the procedures in dictionaries. There are certain ways to store the data in the different types of sequences, and we have highlighted a lot about almost all of them. It is time to discuss the arrays, but before this, it is better to understand the objectives of this lecture:
Introduction to arrays
Difference between contiguous and non-contiguous memory locations
One-dimensional arrays
Functions in arrays
What are Arra ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to Classes in C#. It's my 13th tutorial in C# series and now we are ready to understand this slightly complex subject in C#.
In our previous tutorial, we have seen Introduction to Methods in C# which are used for organizing the code and we can add some code in separate methods to make the Main method simple. Classes are slightly bigger storage capacities than methods. Methods can store code, classes can store methods. So, let's discuss classes in detail:
Introduction to Classes in C#
Classes in C# are referred as storage units for different methods, fields, objects etc. and are used for organizing the code.
In our previous les ...
Introduction
We're glad you could join us for another lesson in our series on programming for the Raspberry Pi 4. The previous chapter covered how to interface the USB barcode scanner with raspberry pi 4. We looked at different types of barcodes and what each stripe represents as well as the different types of barcode scanners available today. We also built a python program for the intelligent shopping cart and now our familiarity with barcodes and scanners and how they function has significantly increased. The benefits and drawbacks of its use were also discussed, but what we're interested in for this article is the transmission of radio frequency signals using the nrf24l01 Module in a raspberry pi 4.
Components
nRF24L01 RF module
Raspberry pi 4

Are you here to learn about Databases and CRUD operations in the C# programming language? If so, then you will be an expert in no time. Learning Databases and CRUD operations in C# is not a piece of cake. But, if you know all the terms and steps of CRUD operations and databases in C#, it will not be rocket science for you. This article contains all the information you should know regarding databases and CRUD operations. So, keep reading till the end!
C# Programming Language: An Overview
We know that you are already aware of the C# programming language. So, here is a quick overview of the C# programming language before we move to the actual topic:
C#, also known as C-Sharp, is an object-intended coding language that operates on the .NET Platform ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at detailed Introduction to Abstract Classes in C#. It's our 19th tutorial in C# series. Today, we are gonna discuss another new concept in C# and I would recommend you to follow these tutorials at least 3 to 4 times, so that these concepts find the right place in your brain and stick there.
C# Abstract Classes are quite similar to C# Interface in many respects, so if you have studied previous tutorial in C# Series, then do read it first. So, let's get started with Introduction to Abstract Classes in C#:
Introduction to Abstract Classes in C#
Abstract Classes in C# are created by using Abstract Keyword, and are used to create abstract members, which have the ...
