What is a CPU-Bound Task? A CPU-bound task is an operation where the program spends most of its time using the CPU for heavy computation, rather than waiting for input/output (I/O). CPU-bound tasks max out …

What is an I/O-Bound Task? An I/O-bound task is any operation where the program spends most of its time waiting for input/output (I/O) operations to complete, rather than using the CPU. I/O = Input/Output → …

Introduction Python is popular for data science, AI, and backend development—but it often struggles with performance bottlenecks due to the Global Interpreter Lock (GIL). When dealing with CPU-bound tasks like data processing, mathematical simulations, or …

Introduction Python developers often face the big question: Should I use multithreading or multiprocessing for concurrency? While both approaches allow you to run tasks concurrently, they solve different problems: Multithreading → best for I/O-bound tasks …

Introduction In modern applications, performance and responsiveness are crucial. Tasks like downloading files, handling requests, or processing data often need to run concurrently instead of sequentially. This is where Python multithreading comes in. It allows …

Introduction: Why Python Generators Matter When working with large datasets, infinite sequences, or streaming data, efficiency is everything. Storing millions of items in memory with traditional lists can be slow and resource-hungry. That’s where Python …

Introduction: Why Custom Versioning in Django Matters As APIs evolve, maintaining backward compatibility while rolling out new features is a major concern. Django REST Framework (DRF) provides several built-in versioning schemes like URLPathVersioning, NamespaceVersioning, and …

Introduction: Why Namespace Versioning Matters As your Django project evolves, API changes become inevitable—new features get added, response formats are updated, and breaking changes sneak in. Without proper versioning, this can quickly turn into a …

Introduction: Why API Versioning Matters In any real-world API, changes are inevitable—you’ll need to introduce improvements, fix bugs, or modify existing endpoints. But making changes to a live API can break integrations for existing users. …

Introduction: Why Use drf-spectacular for API Documentation? Good API documentation is not a luxury—it's a necessity. Whether you're developing APIs for internal tools or exposing them to third-party consumers, your documentation: Saves time debugging API …

Introduction: Why Use ReDoc for Django REST API Documentation? Great API documentation is non-negotiable. Whether you're building public APIs or internal microservices, good docs: Reduce bugs and misunderstandings Help frontend/mobile teams integrate faster Simplify onboarding …

Introduction: Why Swagger API Docs Matter in Django Great code deserves great documentation—especially for APIs. When building REST APIs with Django REST Framework (DRF), clear and up-to-date documentation is critical for: Frontend developers and third-party …

Introduction: Why Testing in Django Matters In modern web development, testing is not optional—it's essential. When building Django applications, especially with Django REST Framework (DRF), you want to be sure your views, models, serializers, and …

Introduction: Why Use APIClient in Django? When developing APIs with Django REST Framework (DRF), testing your endpoints is non-negotiable. Bugs in API logic, security vulnerabilities, or bad request handling can derail a production app. To …

Introduction: Why API Testing with APITestCase Matters In modern web applications, APIs act as the contract between frontend and backend. Even a small change in the backend can silently break functionality—if it’s not tested. That’s …
