Then this will be the default page of Google. For example, if I go to a website such as “/” with nothing after the slash. Here we are creating a new web application. We are creating an instance of the Flask class and calling it app. This current file will represent my web application. Line 1: Here we are importing the Flask module and creating a Flask web server from the Flask module. This piece of code is stored in our main.py. The code lets us run a basic web application that we can serve, as if it were a website. Flask lets us focus on what the users are requesting and what sort of response to give back. It makes the process of designing a web application simpler. What is Flask? Flask (A Python Microframework) It will also figure out what response to send to the user. It will figure out what those requests are dealing with and what they are asking. We will write code that will take care of the server side processing. Then it displays what you asked for on a page in the browser.
The Google Server sends back an HTTP response that contains the information that my web browser receives.

The Google Server receives the request and needs to figure how to interpret that request. What happens is that an HTTP request has been sent to a server.įor example, when I go to my address bar and type, then hit enter, an HTTP request is sent to a Google Server. When you type the name of a website in the address bar of your browser and you hit enter. Let me give you an example of how you use it everyday. The internet uses it to interact and communicate with computers and servers. What is HTTP and What Does it Have to do with Flask? All the code used in the tutorial is available in this GitHub Repository. In each section, I will show pieces of code for you to follow along.
