Although Python has some performance issues (compared to compiled languages) and the notorious GIL (Global Interpreter Lock), its simplicity, large community, and rich library support more than make up for these shortcomings. Recent advances in Python's core technology have also paved the way for modern features like type hints and concurrency—features that were originally missing. Python 3.5 introduces type hints and

FastAPI vs Django/Flask

Django and Flask are two of the most popular Python web frameworks, but they serve different purposes and have different features. This difference could indeed reflect the difference between WSGI and ASGI, as Django has moved to ASGI support, while Flask is still primarily based on WSGI (although Flask can be extended with additional libraries to support ASGI). main difference The DjangoFlask philosophy is "battery-inclusive": almost all built-in tools are included (e.g., ORM, admin panel). Minimalist and lightweight: puts you in control of select libraries and tools. Use cases are ideal for large, complex applications that require a predefined structure. Ideal for** where flexibility is key
