A Python framework, like any other framework, provides a foundation or substructure for your software development project to build on. To be clear, software frameworks render the generic functionality of the application you’re trying to create so that your developers don’t have to start from the ground up. Here, in this blog we will discuss about what is django framework.
What is Django?
Django is a Python-based web application framework that is free and open source. A web framework is a collection of components that make it easier and faster to create websites.
When creating a website, you’ll need a similar set of components: a user authentication system (signing up, signing in, and signing out), a website management panel, forms, and a mechanism to submit files, among other things.

Fortunately for you, others long ago discovered that web developers encounter similar challenges when creating a new site, so they banded together and established frameworks (one of which is Django) that provide you with ready-to-use components.
Frameworks exist to save you time and money when building a new website by preventing you from having to reinvent the wheel.
Why do you need a Framework?
We need to look at the servers more closely to understand what Django is for. The server must first be informed that you wish for it to serve you a web page.
Consider a mailbox (port) that is constantly checked for incoming mail (requests). A web server is in charge of this. The mail is read by the web server, which then responds with a webpage. However, if you want to transmit something, you’ll need some material. Django, on the other hand, is a tool that aids in the creation of content.
What will happen, if someone send a request from your server?
When a request is sent to a web server, it is forwarded to Django, which attempts to determine what is being requested. It starts with a web page address and attempts to figure out what to do next. This is handled by Django’s urlresolver (notice that a website address is referred to as a URL – Uniform Resource Locator – hence the name urlresolver). It isn’t particularly clever; it takes a list of patterns and tries to match them to the URL. Django examines patterns from top to bottom and passes the request to the associated method if something matches (which is called view).
Consider a letter delivered by a mail carrier. As she walks down the street, she compares each house number to the one on the letter. She places the letter there if it matches. The urlresolver works in this manner!
All of the interesting things are done in the view function: we can search a database for information. Maybe the user requested a change to the data? “Please modify the work description of my employment,” for example, might be written in a letter. The view can check if you’re allowed to perform it, then change your job description and send you a message that says, “Done!” The view will then generate a response, which Django will be able to deliver to the user’s web browser.
