  • 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. 

How to Do Web Development with Python?

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. 

1. HTML and CSS

Learning HTML and CSS helps you design and implement websites. Before using complex web development with Python for more substantial websites, it’s important to know how to organise the reactive static sites. A complete understanding of DNS, hosting, HTTPS and browser setups is necessary. 

2. JavaScript

Ensure you are familiar with JavaScript, and understand data types, conventions, variables, control instructions and loops. While implementing JavaScript into the client-side code, follow the fundamentals of the language.

3. DOM and jQuery

It lets programmers add, modify or remove components from the HTML files. Working with JavaScript libraries like jQuery and DOM makes DOM manipulation easy when you have a detailed understanding of the JavaScript fundamentals. You could also use this to learn how to build dynamic websites.

4. Web Frameworks

A web framework is a set of standardised packages and modules that streamline the creation of online applications. It accelerates and facilitates development while improving the scalability and dependability of the products. Use the web application framework of Python to build complex applications much faster.
