Python Coroutines

Python coroutines are a type of function that can pause and resume execution, allowing for cooperative multitasking and asynchronous programming. They are defined using the 'async def' syntax and can be awaited with the 'await' keyword, enabling non-blocking operations like I/O tasks. Coroutines are a core component of Python's asyncio library for building concurrent applications.

Also known as: async functions, async/await, asyncio coroutines, async coroutines, cooperative functions

Why learn Python Coroutines?

Developers should learn Python coroutines when building high-performance, scalable applications that require handling many simultaneous connections, such as web servers, APIs, or real-time systems. They are essential for writing efficient asynchronous code that avoids blocking on I/O operations, improving responsiveness and resource utilization. Use cases include web scraping, chatbots, and microservices where concurrency is critical.
