In .Net C#, there is a function Task.WhenAll
that can take a list of tasks to await them. What should I use in python? I am trying to do the same with this:
tasks = ... # list of coroutines
for task in tasks:
await task
After adding tasks to a list, you should use asyncio.gather
that gives coroutines as an argument list and executes them asynchronously. Also, you could use asyncio.create_task
that takes a coroutine and calls concurrent tasks in the event loop.
import asyncio
async def coro(i):
await asyncio.sleep(i//2)
async def main():
tasks = []
for i in range(5):
tasks.append(coro(i))
await asyncio.gather(*tasks)
if __name__ == "__main__":
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
loop.close()
