How To Make a Web Application Using Flask in Python 3

However, we can install the flask using the above command without creating the virtual environment. Once it is installed, we can create the new virtual environment into a folder as given below.

POST is used to send data to a server to update or create a resource. Most examples remove it for brevity, but you should always be mindful of how you’re accessing untrusted data.

Edit the post and submit the form, then make sure the post was updated.

As a result, the risk of manual maintenance is much lower. Many of the remaining differences between the two frameworks are mostly high-level. Django is often considered the more secure solution than Flask, thanks to its “batteries-included” nature.

Defining datatype along with variable name enforces the user to follow the convention while passing the route name to the server.

There must be a reason why both are popular python-based frameworks in the web development domain. Both Flask and Django are open-source web frameworks used for Python. Both have well-established, mature use communities, are popular and widely supported, and offer developers a way to increase their programming productivity. Django is a free programming language with improved features and performance. Django is preferred by developers because it allows them to use it for standard functions with minimal interference from systems, protocols, and management.

• Django is essentially an open-source web framework on steroids, focused on delivering business value of the product, as opposed to forcing you to make technological decisions.
• Each of them also support a test client that you can send requests to and then inspect and validate parts of the response.
• The choice to go with one framework or language or tool over another depends almost entirely on the context and problem at hand.
• I hope you got a better picture of the use cases of the Flask framework after reading this article.
