advanced patterns when using asyncio.gather with variable number of coroutines in Python 3.10
I need some guidance on I'm updating my dependencies and I'm prototyping a solution and Hey everyone, I'm running into an issue that's driving me crazy. I've looked through the documentation and I'm still confused about I'm trying to use `asyncio.gather` in Python 3.10 to run a variable number of asynchronous coroutines, but I'm working with unexpected behavior. I have a function that generates a list of coroutines based on user input, which I then pass to `asyncio.gather`. Here's a simplified version of my code: ```python import asyncio async def fetch_data(id): await asyncio.sleep(1) return f'Data from {id}' async def main(user_inputs): tasks = [fetch_data(i) for i in user_inputs] results = await asyncio.gather(*tasks) print(results) user_inputs = [1, 2, 3] # This works fine asyncio.run(main(user_inputs)) ``` However, when I change `user_inputs` to an empty list, like so: ```python user_inputs = [] # This causes a question ``` I get the following behavior: ``` RuntimeError: no running event loop ``` I'm not sure why I would receive this behavior with an empty list when `asyncio.gather` should simply return an empty list as well. I also tried wrapping the call to `main` in a try-except block, but it didn't catch the behavior. I’ve reviewed the documentation for `asyncio.gather`, and it seems like this should be valid. Is there some edge case or best practice I might be missing here? Any help would be appreciated! This is part of a larger API I'm building. Is there a better approach? Is this even possible? Thanks for taking the time to read this! Any ideas what could be causing this? My development environment is Ubuntu 22.04. Is there a simpler solution I'm overlooking? I'm coming from a different tech stack and learning Python. Any pointers in the right direction?
