Flask vs. Django – Which Framework to Learn First?

Introduction to Computer Science

As a beginning coder, you’ve likely heard that Python is known as one of the easiest programming languages to learn. It has a number of web frameworks to help you build functional and scalable websites and applications. 

Django and Flask are the two most popular web development frameworks that Python developers learn and use:

While these Python-based web frameworks have their unique features and differences, it can still be difficult to know which framework to learn first. Keep reading to learn the differences between Flask vs. Django, and which is best to start learning at the beginning of your coding journey.

What is Flask?

Flask is a lightweight open source Python web framework that enables developers to easily build functional websites and applications.

Flask is a micro-framework written in Python that doesn’t depend on libraries and tools. It has essential functionalities to provide tools for creating applications in the Python programming language.

Here are some features of Flask:

What is Django?

Django is a mature open source Python-based web framework for developing high-level software applications.

The Django framework contains libraries and an extensive suite of features for the full-scale development of complex applications.

Because of Django’s complexity, one of it’s well-known design principles is DRY, “Don’t Repeat Yourself.” This means it allows you to easily create unique applications without duplications.

Pros & Cons of Django

The full-stack Python-based web framework, Django, also has its own advantages and disadvantages.

Here are the pros of the Django web framework:

The cons of the Django web framework include:

Flask vs. Django: Which is Harder?

Now that you know what these Python frameworks mean and how they function, what about their difficulty levels? 

Which Python-based web framework is harder — Flask or Django?

Because Django is a high-level web framework, it has more learning difficulty when compared to Flask.

This means beginner developers will find exploring Flask to be a more straightforward option than learning Django. 

Below is a comparison chart to help you understand Django and Flask at a glance:

Flask is a micro web framework for Python.Django is a high-level Python-based web framework
The web framework, Flask, is easy to learn.Django is not as simple as Flask and has a steeper learning curve.
There is API support in Flask. Django doesn’t support API.
Flask has lightweight documentation.Django has extensible documentation.
There is no support for dynamic HTML pages in Flask.There is support for dynamic HTML pages in Django.
To use multiple databases in Flask, you need to set up binds.To set up multiple databases on Django, you need to set the default database entry to a custom input.
It does not require any library or tools.Django has its own library.
Flask has minimalistic features for web development.Django is a full-stack web development framework for Python.
Flask has limited administrative tools.Django offers an officially supported administrative tool.
Flask provides just the perfect support for simple applications.Django is ideal for large-scale complex projects that require several features.
Flask has no default template engine and uses Jinja2 instead.There’s a default template engine in Django to provide full-stack support.
Some companies using the Flask framework for backend development include Reddit, Airbnb, Uber, and Netflix.Some companies using the Django framework for backend development include Spotify, Pinterest, Disqus, and Instagram.

Should I Learn Flask or Django?

It’s a big question, especially if you’re at the beginning of your coding journey.

Django is a mature framework for Python, but it is simple to use. However, it poses more learning difficulties in comparison to Flask’s micro-framework.

While Django is incredibly popular and used amongst experienced developers, beginner developers may have a better learning experience starting with the Flask framework because of its simplicity.

Because of this, we recommend starting with Flask. After learning Flask’s framework, you’ll have the essential programming skills to create functional websites and applications.

Once you feel comfortable with Flask’s framework, you can advance to Django to learn how to develop for more complex software projects.
