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.
Python lists are one of the most common and popular data structure of python. Almost every python programmer uses them for writing great programs in python. Python lists are almost similar to the vectors in C++ or arrays in Javascript. Lists are mutable, which makes them editable after creation. Lists can contain elements like numbers, strings, dictionaries, tuple, boolean, lists, and any other python object.
Python is a great programming language; it is used in many fields like Web Development, Machine Learning, Data Science, Computer Vision, etc. In python, we can easily write programs that output data into the console. But writing data to the console is not the best thing when we required that data for further processing.
Javascript is a great language for the web; we can perform many tasks using it, making the web more dynamic. We can also use the scripting language to collect the user location or track the user. The user location that we collect can be used for several things like tracking our customers, better mapping facility, recommending users something based on their location, etc. A simple application of location-based services is Food ordering Services, which get the user location and suggest nearby restaurants.
SVG or Scalable Vector Graphics is a popular image format based on vector graphics primarily written in XML. They are gaining high popularity currently in web designing due to many of the advantages provided by them. SVGs are primarily used in web design. They are more powerful than any of the image formats available for the web because of the ability to be manipulated using CSS and Javascript.
The PDF or Portable Document Format is a popular and common file format used to present and exchange documents. PDFs are used for many things like creating EBooks, digitally signed agreements, password-protected files, etc. Adobe originally invents PDF, but it is now open standard and maintained by the International Organization for Standardization (ISO).
JSON is a widely used syntax for storing and transferring data over networks. They are used in web APIs provided by both small scale and large scale websites. In this tutorial, we will see the practical use of JSON in python by accessing an API provided by GitHub to access repository data.
Python Rich Library is a great library for writing text with color and style them in the terminal. It can be used to display tables, markdowns, progress bars, and syntax-highlighted code in the terminal. Though the library is not too old and the first version was released on 10 November 2019, it gained high popularity in the python community and Github.
JSON or Javascript Object Notation is a syntax used for storing and exchanging data over a network. It is inspired by the Javascript programming language used basically in front-end web development, but later it becomes independent and available for almost every programming language, including python.
