After reading and comprehending the in-depth information about both web frameworks, it is easy to conclude that they have their own advantages.

  • POST is used to send data to a server to update or create a resource.
  • Flask is preferred by programmers with more coding experience or who require more control over the app design.
  • Files are temporary stored on server and then on the desired location.
  • Flask will make your life easier than Django if you’re looking to create a simple web app with a few static pages.
  • It allows you to create an application with a tiny amount of code.

In the above example, we’ve 3 simple routes and their functions hard-coded in the traditional manner. This method takes a user-defined input through their URL. Based on the input of the `country` variable, `url_for()` method redirects it to the appropriate function call. To understand Flask, we need to understand what is the traditional web framework.

This in flask can be done by using the method flash() in Flask. It needs an HTML form with enctype attribute and URL handler, that fetches file and saves the object to the desired location. Files are temporary stored on server and then on the desired location. Nowadays, the web frameworks provide routing technique so that user can remember the URLs.

Even before the roll-out stage—Python is ideally suited for designing and testing prototypes as well, allowing them to iterate and develop, reaching the finished product quickly. In the above example, let’s replace the content of `success()` function. Reversing of routing is far more descriptive than hard-coding (hard-coding is bad practice) of routes. `redirect` & `url_for()` need to be imported separately, to begin with.

Any CherryPy-powered web application is a standalone Python application with its own embedded multi-threaded web server and runs on any OS with support for Python.

Zope 2 is both a web framework and a general purpose application server, today it is primarily used by ContentManagementSystems. Zope 3 is both a standalone framework and a collection of related libraries, which are also included with newer releases of Zope 2. All of the Zope frameworks include the ZODB, an object database for Python. A web application may use a combination of a base HTTP application server, a storage mechanism such as a database, a template engine, a request dispatcher, an authentication module and an AJAX toolkit. These can be individual components or be provided together in a high-level framework. The back end is the foundation on which the application or website is built on.

It supports a lot of extensions that we can add to any application features that we like. In the case of a GET request, you render an edit.html template passing in the post variable that holds the returned value of the get_post() function. You’ll use this to display the existing title and content on the edit page. Now that you’ve passed the posts you fetched from the database to the index.html template, you can use a for loop to display each post on your index page. You might have guessed that making another HTML template would mean repeating most of the HTML code you already wrote in the index.html template.
