A Do-While loop checks a condition after initially executing the statement. At any given point, a do-while loop is executed at least once. This is what is referred to as a post-test loop. Since Python does not explicitly handle do-while, we will demonstrate with examples of how to emulate the process.
Doubly linked lists are different from singly-linked lists because travel is both ways. The key differentiating factors in a doubly-linked list are the first and last elements because they perform a critical role in this data structure’s function. Therefore, it is common to hear of data being carried from two connecting fields, which are previous and the next.
Data Visualization is one of the most important things for a data scientist or anyone working or analyzing data. Visual data is easier to understand by a person than raw data, so it is more important to visualize data while performing presentations or analyzing data. We can also take out powerful insights from the raw data if visualized adequately.
Under the Python programming language domain, a String is defined as character data presented in an ordered sequence. What is character data? When you are working on an office suite software or word processing app, the bottom of the screen or monitor you are using always keeps a record of the word count and characters. Anything that you type on the Keyboard and is displayed on the interface of this word software or even a source code editor qualifies as the definition of character data.
QR codes are an important part of today’s world. They are used in many modern applications to store large data visually easily. They are nowadays used in many money transaction apps for easily getting the information by scanning the QR Code. They are also used by applications to give authentication to another device by scanning the Code easily.
Python is not just any programming language; it is general-purpose, high-level, and interpreted. Many coding enthusiasts and developers are turning to Python because of its remarkable design philosophy. It strongly purports code readability through its significant use of notable whitespace. Therefore, this article seeks to explore the effectiveness of the Python programming language in looping useful code. The world of computing defines a loop as a controlled flow of iterations.
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.
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.
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.
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.
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.
As of 2017, Python joined the top 10 slots that defined popular programming languages in the world. This reference is a direct quote from the TIOBE Programming Community Index. As of now, Python is among the top 3 candidates on this list. However, this mileage defines Python as the most uncomfortable programming language. Reason? Being top 3 is not enough as it wants to be the only top candidate.
