In this tutorial, we will learn to perform some basic operations on python lists such as sorting, calculating the length of a list, etc. To follow this tutorial, python should be installed on your computer so you can try each of the codes by writing it on your own. It is also recommended to use an IDE(Integrated Development Environment) such as the open-source Visual Studio Code for writing programs fast and efficiently. Now, let us start our tutorial with the introduction of python lists.
In this article, we will go through deploying a flask application using AWS Beanstalk. Also, in this example, we will use a REST API, but the process is identical if you take a vanilla flask web application.
Python is a very popular language that can be used to perform a wide variety of tasks. We can use python to perform operations like Machine Learning, Data Science, web applications, Mobile applications, Automation, etc., very easily. In this tutorial, we will use python to access weather data from an API for a specific area.
Ctags is a handy tool for navigating any programming language’s source code. Ctags parses identifiers, methods, classes, and other elements from the source code and saves the index in a tag file. Each tag is kept in its line. Ctags is a program that is supported by a wide range of programming languages. Functions, variables, class members, macros, and other items may be indexed depending on the language. These tags allow a text editor, a code search engine, or another utility to quickly and readily discover definitions.
We’ll learn how to download and install Sublime Text 3 and run Python scripts in the Sublime Text 3 editor. We will also examine the installation of packages. So let’s get started.
Flask is a WSGI web application framework that is lightweight. It’s built to get started simple and quick, with the flexibility to scale up to more sophisticated projects.
