Overview of this book

Do you know what is common between Netflix, Instagram, Spotify, Dropbox, and Uber? All these applications are made in Python. There is no doubt that Python is one of the most popular programming languages in the modern technological world. This course will teach you Python and web development skills that will help you to build real-time applications. The course begins with an introduction to Python fundamentals, and teaches you how to install Python 3.4.3 on your machine. Moving ahead, you will understand how the internet works, find out how Python retrieves data, and get an overview of the MongoDB database. Next, you will apply what you have learnt, and use Flask to create your first web application, a simple blog where users can register and publish posts. Then, you will step up your game and create a web application in Python to receive notifications when prices of items in online stores go down. Towards the end, you will deploy your application to Heroku by integrating GitHub, and also learn how to manually deploy on a server using Ubuntu. By the end of this course, you will develop essential Python skills needed to build robust web applications.
