• Seamless Integration and Compatibility: Python integrates with other technologies easily, which makes it flexible for web development. It augments databases, such as SQL-based databases (MySQL, PostgreSQL, and SQLite) and NoSQL databases (MongoDB). Python offers compatibility with web servers, caching systems, message queues, and APIs, which lets developers efficiently integrate various components and services.
• Testing and Debugging Excellence: Python provides robust testing frameworks like unittest and pytest that simplify writing and executing tests for web applications. Debugging tools such as Integrated Development Environments (IDEs) offer great debugging capabilities, like helping developers detect and fix issues quickly.
• Rapid Development of Web Applications: The focus of Python on simplicity and productivity lets developers build web applications swiftly. Using pre-built modules and libraries helps developers leverage the present solutions without reinventing the process. This rapid development is advantageous to small-scale businesses and startups, prioritising time-to-market. 

Web development in Python is more straightforward and works exceptionally well compared to other object-oriented programming languages. Web development on Python involves developing and managing websites. It includes building a single static site of simple text or could be developing complex web applications, social media, online storefronts, etc.

Web developers can pick their choices for front-end, back-end or full-stack specialisations. While the front end deals with client interactions, the back end focuses on tech infrastructure and communities using a database and full-stack platforms. As Python frameworks are conducive, most Python developers use a combination of Python and Javascript to construct web projects. You can adopt the following process to build a website with Python. 

• Learn the fundamentals of Python: Familiarise yourself with the basics of Python programming for web development, which include data types, syntax, control structures and functions. You can refer to the books or online tutorials to get started.
• Understand HTML, CSS and JavaScript: Know the basics of web technologies such as HTML for markup, CSS to enable styling and JavaScript to ensure client-side interactivity. These are vital for understanding and building web pages.
• Choose a web framework: Choose a Python web framework that aligns with your project's requirements. Every framework has its own features and learning curve, hence, browse their resources and documentation to make informed choices.
• Front-end development: Improve your web development skills by practicing well-known front-end libraries and frameworks like Vue.js, React, Angular, etc. These let you build interactive user interfaces and enable communication with backend APIs.
• RESTful API development: If API development is a part of the project, understand RESTful principles and design patterns. Leverage your chosen web application framework of Python to build APIs that present functionality and data to other front-end interfaces or applications.
• Authentication and authorisation: Define the concepts of user authentication and authorisation. Understand how to implement secure user registration, access control mechanisms and logins with built-in features or extensions for your web framework.
