Frameworks make developers’ lives easier by offering them a structure for application development. They automate the implementation of common solutions, cutting development time and allowing developers to focus more on application logic instead of routine elements. In this article, we share our own list of the top ten Python web frameworks that we believe will be useful on your way to becoming a professional backend developer and improving your existing skill set. Keep in mind that these frameworks are listed in no particular order: we’ve focused on showing what you’re able to do as opposed to telling what you should do. web frameworks Some things to consider When deciding which framework to use, look at the size and complexity of your project. If what you’re looking to develop is a large system packed with features and requirements, a full-stack framework might be the right choice. If your app is on the smaller and simpler side, you should probably consider a microframework. You can find information about the type and focus of some frameworks here. A final decision, though, should come from your own understanding of your project and the tasks you want to simplify. here However, frameworks can also stand in the way of development. When choosing a full-stack framework, you’re often signing up for a set of limitations. Of course, you can find ways to work around them, but be careful you don’t spend more time fighting for your own freedom than you would have writing an app in pure Python. Python Full-stack frameworks Django Official Website | GitHub | PyPI | Awesome Official Website GitHub PyPI Awesome GitHub Stars: 31,592 | GitHub Forks: 13,361 Django is a free open-source full-stack Python framework. It tries to include all of the necessary features by default as opposed to offering them as separate libraries. Some of the exemplary features of Django are its authentication, URL routing,template engine, object-relational mapper (ORM), and database schema migrations (Django v.1.7+). authentication URL routing, template engine object-relational mapper database schema migrations Django uses its ORM to map objects to database tables. The same code works with different databases and isn’t difficult to transfer from one database to another. The main databases that Django works with are PostgreSQL, MySQL, SQLite, and Oracle, but third-party drivers allow you to use others as well. PostgreSQL MySQL SQLite Oracle Here at SteelKiwi, we use Django as our primary framework for backend development.

CherryPy Official Website | GitHub | PyPI Official Website GitHub PyPI GitHub Stars: 595 | GitHub Forks: 161 CherryPy is an open-source, minimalist web framework. It makes building Python web applications no different than building any other object-oriented program. In fact, a CherryPy-powered web app is a standalone Python application that embeds its own multi-threaded web server. CherryPy apps run on any operating system that supports Python (Windows, macOS, Linux, etc.). They can be deployed anywhere you can run an ordinary Python app. You don’t need Apache for CherryPy apps, but you can run a CherryPy app behind Apache just as well as you can run it behind Lighttpd or IIS. Apache Lighttpd IIS CherryPy isn’t a very limiting framework, as it allows you to use any type of technology for templating, data access, and so on. However, it’s still able to handlesessions, statics, cookies, file uploads, and everything else that a web framework typically can.
