Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to use String in Python. It's our 3rd tutorial in Python series. We have discussed strings in our previous lecture How to use Data Types in Python.
String is a most commonly used data type in python that's why I have created a separate lecture on it. Python has many built-in string operations, which we will discuss today in detail. So, let's get started with String in Python:
How to use String in Python
String Data Type is used to store or collect one or more characters or sequence of characters, we can place any alphanumerical or special character in a string.
Let's create a string in python, it has a simple syntax, as shown below:
first_var = "He ...
Hello friends, I hope you all are doing great. In today's lecture, we will have a look at the I2C Communication with STM32 Microcontroller board. I am going to use the Nucleo board for today's lecture. In the previous lecture, we have discussed STM32 Serial communication both in Interrupt Mode and polling Mode. Today, we will study another way of communication(i.e. I2C) with STM32. So, let's first have a look at what is I2C Communication:
What is I2C Communication?
I²C (Inter-Integrated Circuit) is a two-wire serial communication system used between integrated circuits. Like any serial protocol, one of its advantages is that of using only two lines that transmit or receive a sequence of bits, the limit is the communication speed which has been improved over the years.
The bus was conceive ...
To become familiar with the world of microcontrollers it is necessary to have a development board (also known as a kit), which generally allows you to start working on it easily. Fortunately, the ST provides a wide portfolio of development boards. In this guide, we will describe and use the Nucleo board.
The Nucleo has been introduced a few years ago and its line is divided into three main groups:
Nucleo-32;
Nucleo-64;
Nucleo-144.
Nucleo-32 Development Board
The number of pins available, so the package, gives the name to the board: Nucleo-32 uses an LQFP-32 package; Nucleo-64 and LQFP-64; Nucleo-144 an LQFP-144. The Nucleo-64 was the first line introduced and counts 16 different boards.
The Nucleo boards have interesting advantages compa ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to setup MVC in ASP.NET Core. It's our 6th tutorial in ASP.NET Core series. So far, we have covered all the basic concepts in ASP.NET Core and are now ready to get our hands on MVC.
If you remember, when we were creating this project in Introduction to ASP.NET Core, we have selected Empty Template as we want to build our application from scratch. But if you want, you can also select MVC template and all these files, which we are going to create, will automatically be created in it. So, let's see How to setup MVC in ASP.NET Core:
How to setup MVC in ASP.NET Core ???
MVC in ASP.NET Core is an architectural design pattern, implemented by Microsoft.AspNet ...
In today's digital age, remote workers are on the frontlines of an invisible war, battling unseen cyber threats. As they maneuver through the complex terrain of remote work environments, they're confronted with potential hazards at every turn.
From a compromised network and data breach to phishing attacks, remote workers are tasked with safeguarding the organization's digital fort.
Building a cybersecurity culture
The remote workforce is instrumental in building a cybersecurity culture where everyone becomes their own expert, advocating for security measures and promptly reporting suspicious activities. This culture is particularly significant in virtual office environments, where workers are the custodians of sensitive data.
As remote employees constantly face cybersecurity challenges ...
Hi pals! Welcome to the next deep learning tutorial, where we are at the exciting stage of TensorFlow. In the last tutorial, we just installed the TensorFlow library with the help of Anaconda, and we saw all the procedures step by step. We saw all the prerequisites and understood how you can follow the best procedure to download and install TensorFlow successfully without any trouble. If you have done all the steps, then you might be interested in knowing the basics of TensorFlow. No matter if you are a beginner or have knowledge about TensorFlow, this lecture will be equally beneficial for all of you because there is some important and interesting information that not all people know. So, have a look at the topics that will be discussed with you in just a bit.
What is a tensor?

Hello guys, hope you are doing good and enjoying your lives. Today, I am going to introduce you to the blocks of a blockchain. I gave you an understanding of blockchain, its characteristics, and some idea about accounts and wallets in my previous tutorials, and today my article is about the structure of a block in the blockchain.
I will first define the block before going into the details about its structure. So let’s start without any further delay.
Block in Blockchain
A block is actually the building block or the key element of a blockchain.
The definition of a blockchain is based on its blocks. As I defined in my previous posts, a blockchain is a chain of multiple blocks.
Blocks contain transac ...
If you plan to run a start-up, it helps to have some basic understanding of IT management. Here are some key pointers on how best to manage your business IT systems:
You should know how your IT systems work and how they can be managed. This will help you keep them working well, which is especially important if your business depends on them for important functions like payroll or customer service. The earlier in the process that someone understands their role and responsibilities in running the company's technology, the better off they'll be when troubleshooting problems arise later on down the road.
How to Manage IT Management for Start-Ups
Make sure your hardware and software are secure.
Ensure that you have the right licenses for your ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at Form Validation in ASP.NET Core. It's our 15th tutorial in ASP.NET Core series. In our previous lecture, we have created a Registration Form for our engineering website. But we haven't added any validations on the submitted data.
So, even if users don't fill any boxes and just hit the Register Button, a new user will be created without any personal info. So, today we will place some checks on these text boxes to validate the user submitted data. So, let's get started with it:
Form Validation in ASP.NET Core
Validations in ASP.NET Core are available in the form of attributes & Tag Helpers.
Validation Attributes are applied on Properties in Model clas ...
Hello everyone, I hope you are doing great. In this article, we will talk about C# TextBox Control. In the previous articles, you have already get familiar with C# Button Control & C# Label Control, this is the sequence of those. In short C# TextBox Control is just same as the other expect some few changing. Before getting started with C# TextBox you must have knowledge of previous concepts. It's not essential but it will give you the edge to understand the advanced elements of C#.
C# TextBox is used to get input from users or it can also be used to display some values to the user. The textbox is a container for text blocks, you can take inputs or show the text as you required in the form of paragraphs. If you used TextBox as the input field t ...
