Python Library vs Python Framework

Understanding the difference between Python libraries and frameworks is crucial when selecting the right tools for your project. A Python library provides reusable code that can be incorporated into any program. In contrast, a framework dictates the structure of your application and provides a foundation upon which you build your app.

Types of Python Frameworks

There are mainly two types of Python frameworks:

• Full-stack frameworks: These provide all the components needed for web application development, such as authentication, form handling, and more.
• Micro-frameworks: These are lightweight frameworks designed for smaller applications that allow developers to add only the components they need.
