The World Wide Web (WWW) is a combination of all resources and users on the Internet that are using the Hypertext Transfer Protocol (HTTP). The Web is the common name for the World Wide Web, a subset of the Internet, consisting of the pages that can be accessed.
Define Web Applications
Aweb applicationor web app is a client-server computer program that the client runs in a web browser.
Aweb applicationis a computer program that utilizes web browsers and web technology to perform tasks over the Internet.
The application can be as simple as a message board or a contact form on a website or as complex as a word processor or a multi-player mobile gaming app that you download to your phone. Web application architecture defines the interactions between applications, middleware systems and databases to ensure multiple applications can work together. When a user types in a URL and taps “Go,” the browser will find the Internet-facing computer the website lives on and requests that particular page. The server then responds by sending files over to the browser. After that action, the browser executes those files to show the requested page to the user. Now, the user gets to interact with the website. With client-side code, languages used include:
A web-based application is any application that uses a website as the front-end, allowing users to access the application from any device. Companies such as Google have
championed the web-based application industry, using the Chrome browser platform to facilitate the creation of open-source web application development which can be utilized
by companies looking to target these digital users.
Web applications include online forms, shopping carts, word processors, spreadsheets, video and photo editing, file conversion, file scanning, and email programs such as Gmail, Yahoo, and AOL. Popular applications include Google Apps and Microsoft 365.

How to make a web app with python?
A computer; any will do!
No software required, we’ll install everything as we go.
We will also install Python in the course! We can use either Python2.7 or Python3.5
The idea behind creating a Python-driven web application is that you can use Python code to determine what content to show a user and what actions to take. The code is actually run by the web server that hosts your website, so your user doesn’t need to install anything to use your application; if the user has a browser and an Internet connection, then everything else will be run online.
The first thing that you will need is a web hosting plan that allows and supports the ability to run Python code. Since these usually cost money, we’ll stick with a free alternative that is one of the simplest to set up: Google App Engine, which uses a web framework called webapp2. Getting started with Google App Engine will be the quickest and easiest way to begin learning about web application development in Python.
First, go to download and install the appropriate Python SDK (Software Development Kit) for Google App Engine. The Google App Engine Launcher, which will help with getting your web applications online.
Create a new folder. We will write a very simple Python script that can “respond” with the content of your web page:
print “Content-Type: text/plain”
print “Congratulations, it’s a web app!”
Save this code in a script named hello.py inside your “first_app” folder.
Before we can run our web application, we need to provide the App Engine with a configuration file. This is the file that the webserver will use to get information about what Python code we want it to run. Open up any text editor and copy the following text into a new file:
– url: /.*
Now name this fileapp.yamland save it in the same folder as the Python script.
Okay, now we can finally take a look at our application!
