Coroutine

Asyncio By Example: Implementing the Producer-Consumer Pattern

Jul 9, 2024 python coroutine tech

The Most Basic Case With corountines, we can define a produer and consumer without any need for threads. This simplifies our code and makes it more efficient. import asyncio async def producer(): for i in range(6): await asyncio.sleep(0.2) yield i async def consumer(): async for i in producer(): print(i) async def main(): await asyncio.gather(consumer()) asyncio.run(main()) 0 1 2 3 4 5 Work with Heavy IO When working with heavy IO operations, we need to be careful not to block the event loop.
