Making the Most of asyncio: Adding Tasks to Event Loops

Author: Mohan Ganesan

Date: Mar 25, 2024

The asyncio module in Python provides infrastructure for writing asynchronous code using the async/await syntax. The event loop is at the heart of asyncio and manages task execution. Enqueue tasks with loop.create_task() or ensure_future().

How many times should asyncio run () be called python ?

Author: Mohan Ganesan

Date: Mar 17, 2024

The asyncio.run() function is used to run the top-level entry point of an asyncio program. It should generally only be called once per program. Calling it multiple times can lead to unexpected behavior. Here are some tips on using asyncio.run(): Call it only once at the top level of your program. Use asyncio.run() in simple programs and scripts. If you do call asyncio.run() multiple times, make sure the event loop from the previous call is fully closed first.
