Introduction
In the dynamic realm of web development, Python has emerged as a robust and scalable language for crafting web applications. Among the array of frameworks available, Flask and Django shine as favoured choices for developers due to their simplicity, flexibility, and scalability. This guide extensively delves into the intricacies of Python web application development, focusing on Flask and Django, and explores how these frameworks can be harnessed to create potent applications. If you are embarking on a Python course, comprehending these frameworks is indispensable for your foray into the world of web development.
WHAT IS FLASK?
Lightweight and Microframework:
Flask is often labelled a “microframework” as it furnishes the essentials for web development without imposing overly rigid restrictions or pre-defined patterns. Developers can select and integrate components as required, rendering it flexible for a diverse range of applications.
Minimalistic and Easy to Learn:
Flask adopts a minimalistic approach, making it easily comprehensible for beginners. Its simplicity enables a quick start, facilitating the building of applications with concise code.
Extensibility:
Designed to be extensible, Flask empowers developers to incorporate features as required. While certain components are not included by default (e.g., an ORM for database operations), developers can seamlessly integrate third-party libraries for such functionalities.
Jinja2 Templating:
For rendering dynamic content in HTML templates, Flask employs the Jinja2 templating engine. This separation of concerns between application logic and presentation enhances code readability.
Best Suited For:
Small to medium-sized projects
Projects prioritisation flexibility and minimalism
Developers who prefer a hands-on and modular approach to web application development
WHAT IS DJANGO?
High-Level and Full-Stack Framework:
Django stands as a high-level, full-stack web framework, equipped with built-in features like an ORM (Object-Relational Mapping), an admin interface, and a robust templating system. Following the “batteries included” philosophy, it provides numerous tools and functionalities out of the box.
Opinionated and Convention Over Configuration:
Django is opinionated, adhering to a set of conventions that developers are expected to follow. Embracing the “don't repeat yourself” (DRY) philosophy, it minimizes redundancy and encourages code reuse.
Admin Interface:
Featuring a powerful and customizable admin interface, Django automates many administrative tasks, simplifying backend management.
Django ORM:
Django incorporates its own Object-Relational Mapping (ORM) system, enabling developers to interact with databases using Python code rather than raw SQL queries.
Best Suited For:
Large and complex projects
Projects where rapid development and convention-based structure are advantageous
Developers who appreciate an integrated and feature-rich framework for web application development
