Top Python Frameworks for Web Development in 2024

Python has become one of the most popular programming languages for web development over the past few years. Its high productivity, vast collection of libraries and frameworks, and easy readability make it a go-to choice for many developers.

As Python continues to grow in usage and capability, a number of robust and full-featured web frameworks have emerged to help developers build powerful and scalable web applications more efficiently. Choosing the right framework can significantly impact the speed, performance, scalability and maintainability of Python development firm web projects.

As developers evaluate different frameworks for web development, they may also consider the importance of partnering with the right software development company for specific project needs. Companies like Jelvix (https://jelvix.com/services/software-development) offer comprehensive software development services that can complement the strengths of Python frameworks by providing expertise in building custom solutions. This can be especially valuable when integrating a variety of components or scaling up complex web applications to meet unique business requirements.

Django

Django is arguably the most popular Python web framework today, used by companies like Instagram, Spotify, YouTube and Dropbox. It is expected to continue leading the market in 2024.

Django follows an MVT (Model-View-Template) architectural pattern. It is a batteries-included, high-level framework providing many out-of-the-box capabilities for rapid web development:

  1. Object-relational mapper (ORM) for database access.
  2. Easy admin interface creation.
  3. Form handling.
  4. User authentication and permissions.
  5. Caching.
  6. Internationalization.

Key strengths:

  1. High scalability is proven by large-scale websites.
  2. Extensive ecosystem of 3rd party packages and support.
  3. Robust security protection against attacks like SQL injection, cross-site scripting etc.
  4. Powerful default admin interface.

Best use cases:

Django is a great choice for building content-driven websites and web applications with data-driven user interactions. Common examples include:

  1. Content management systems.
  2. News sites / blogs.
  3. E-commerce stores.
  4. Social platforms.
  5. Custom admin interfaces.
  6. Database-driven web applications.
