Building Modern APIs with Python and FastAPI

Python developers need robust, high-performance tools to build modern web services. FastAPI provides the speed and clarity required for complex backend development, making it an excellent choice for contemporary applications. This course guides you from foundational Python concepts and asynchronous programming to developing fully functional, data-driven APIs. You will gain the skills necessary to build scalable backends that integrate databases, handle scheduled tasks, and communicate with external services like AI models and messaging platforms. What you'll learn: * Understand the core principles of API design, Pydantic data modeling, and asynchronous programming in Python. * Develop robust endpoints using FastAPI, complete with dependency injection and comprehensive type hinting for safety. * Integrate SQL databases using an asynchronous ORM for persistent data storage in your web services. * Practice implementing basic testing strategies using pytest to ensure API reliability and maintainability. * Configure background tasks and scheduling mechanisms for autonomous operations within the application. * Apply patterns for connecting your backend to external AI model APIs and building simple content generation features. * Build a functional messaging interface, such as a Telegram bot, that interacts directly with your API endpoints. The course starts with essential setup and API fundamentals, progresses through data handling and structure, then moves into integrating external services and advanced deployment considerations using containerization basics. This course is designed for beginner Python developers who want to learn professional backend development. No prior experience with web frameworks or API design is required.
