Web scraping is one of the most trending topics these days. Due to the advent of Big Data for Machine Learning and Artificial Intelligence, Web scraping has become an essential tool to collect as much data as possible from the modern web. Python is a great programming language that can be used for collecting data from the web. We have many libraries like selenium, BeautifulSoup, Scrapy that can be used for mining the web and collect data.
HTML is an acronym for Hypertext Markup Language. It’s used for designing static web pages. Html is normally displayed in web browsers. PDF is an acronym for Portable Document Format. It’s easy to read and share since it’s in a printed, electronic format.
In this tutorial, we will learn how to use the python if/else statements, which will help us deal with decision making in our python program. We will also look at some practical examples to see how it works. To follow this tutorial, you need to have python installed in your system; if you don’t have python installed, you can follow our guide on installing python on Linux.
Before we dive into the tutorial and learn about overloading, let’s first discuss overloading types. Overloading is of two types.
In our previous Django tutorial, we learned how to install this web framework on your Windows devices and create our first Django project by simply running a few commands. As you might know by now, Django provides programmers with rapid development features, and thus, you won’t have to spend your precious time reinventing the wheels. As such, this web framework also comes with its own built-in login system that we’ll teach you how to use in this article.
Taking input from the user is an important part of creating a program, and there can be many ways to take input to use it in our program. One such way is reading data from a file. Taking input from the file may be a bit tricky and difficult to grasp, but it is beneficial for storing a large amount of data.
Django is keen on adhering to the MVC (Model View Controller) convention that many frameworks follow. However, the framework is keen on working with its own control rules. Since the control you need when dealing with your Django apps is not isolated, Django is sometimes called an MVT application with the View component bridging the Model component and Template component of your apps.
Python lists are one of the most powerful and useful data structures. We can use lists to store data in a sequential way as we do with arrays in javascript or vectors in C++. In this tutorial, we will learn how to sort a list in python. We will use the sort() method of the python list and the python’s built-in sorted() function to sort the list and see some hands-on examples on customizing the sorting as our requirements.
To deeply understand how real-world objects are related to programming, we must have an idea of object-oriented programming. So, what are objects? Objects are data items that comprise member functions and attributes.
The knowledge of the correct version of python is important for many tasks. For example, we may want to install a library that requires a specific version of python to check if our system has that version already installed. For example, in the Terminal formatting tutorial using rich, we have learned about a library called rich, which is used for terminal formatting in python. Still, the library requires Python 3.6.1 or later installed in the system.
Java is an object-oriented programming language that can be used to develop desktop applications, web applications, android applications, games, database connections, etc. In this article, we are going to study how to compare strings in Java. In java, a String is a data type or an object that is used to store text. The string object contains characters that are enclosed by double-quotes.
In this tutorial, we will learn how to create virtual environments in Python. We will first look at what is a virtual environment and why we need it and then see how to can we create it and use it. We will be using the virtualenv library for creating virtual environments.
