Pros:

  • Rapid development with many built-in features.
  • Excellent for building secure and scalable applications.

Cons:

  • Can be overkill for simple applications.
  • Somewhat monolithic, less flexible for smaller projects.

2. Flask

Description: A minimalist, lightweight framework that provides the essentials to build web applications.

Highlights:

  • Simple and flexible; provides basic tools for web development.
  • Easy integration with extensions for added functionality.
  • Suitable for microservices and small projects.

Pros:

  • Lightweight and easy to use for small applications.
  • Highly customizable and flexible.

Cons:

  • Requires third-party extensions for advanced features.
  • Not ideal for large-scale applications without heavy customization.

3. FastAPI

Description: A modern web framework focused on performance and building APIs.

Highlights:

  • Fast performance, based on Starlette and Pydantic.
  • Automatic OpenAPI documentation generation.
  • Supports async programming natively.

Pros:

  • Extremely fast, ideal for building APIs and microservices.
  • Great support for async programming.

Cons:

  • Relatively new, so community support is still growing.
  • Not ideal for full-stack web apps without additional components.

4. Pyramid

Description: A flexible framework for both small and large web applications.

Highlights:

  • Highly customizable, with extensive configuration options.
  • Supports multiple databases and templating engines.
  • Good for building both simple and complex apps.

Pros:

  • Highly flexible and configurable.
  • Ideal for developers looking for more control.

Cons:

  • Steeper learning curve compared to frameworks like Flask.
  • Smaller community compared to Django or Flask.

5. Bottle

Description: A fast and simple micro-framework for building small web apps.

  • Fast and scalable for handling large numbers of concurrent connections.

Pros:

  • Great for real-time web applications.
  • High performance for concurrent handling.

Cons:

  • More complex to use than traditional frameworks.
  • Can be overkill for simpler, synchronous applications.

7. CherryPy

Description: An object-oriented framework that allows developers to build web applications in a simple, clean way.

Highlights:

  • Provides its own web server, making it easy to deploy.
  • Scalable and capable of handling large applications.
  • Supports WSGI and integrates with other web servers.

Pros:

  • Simple, minimalistic design.
  • Flexible and works well with existing Python libraries.

Cons:

  • Less popular, so fewer resources and community support.
  • Lacks some modern features found in other frameworks.

8. Web2py

Description: A full-stack web framework that includes everything you need to build, deploy, and maintain web applications.

Highlights:

  • Includes a web-based IDE for easy development and deployment.
  • Built-in support for various databases and form handling.
  • Provides a built-in ticketing system for error tracking.

Pros:

  • Excellent for rapid development and deployment.
  • No external dependencies required.

Cons:

  • Less flexible for large-scale projects.
  • Web-based IDE can be limiting for some developers.

9. Falcon

Description: A lightweight framework for building fast, high-performance APIs.

Highlights:

  • Optimized for building RESTful APIs.
  • Focuses on minimalism and performance.
  • Easy to integrate with other Python libraries.

Pros:

  • Extremely fast and efficient for API development.
  • Great for handling high loads with low latency.

Cons:

  • Not as feature-rich as larger frameworks like Django.
  • Lacks built-in authentication and ORM.

10. Sanic

Description: A web framework designed for building fast, asynchronous web applications.

Highlights:

  • Asynchronous by default for better performance.
  • Supports WebSockets and HTTP/2.
  • Designed for speed, ideal for APIs and real-time applications.

Pros:

  • Great for high-performance, real-time applications.
  • Easy to write asynchronous code.

Cons:

  • Relatively new, so fewer resources and community support.
  • Not ideal for traditional, synchronous web applications.

Each of these Python frameworks brings unique strengths to the table, whether you are building a small, fast API or a large, scalable web application. The choice of framework depends on the complexity, scalability, and performance needs of your project.
