Notes

asyncio.run() gets the event loop, runs tasks until they're complete, and closes the event loop. Introduced in Python 3.7 and replaces asyncio.get_event_loop() and loop.run_until_complete(). E.g.

asyncio.run(main())

rather than:

loop = asyncio.get_event_loop()
try:
    loop.run_until_complete(main())
finally:
    loop.close()

async.gather will schedule multiple async tasks at once. Waits for all tasks to be completed, returns list of results.

 * `asyncio.run()` gets the event loop, runs tasks until they're complete, and closes the event loop. Introduced in Python 3.7 and replaces `asyncio.get_event_loop()` and `loop.run_until_complete()`. E.g.

{{{#!highlight python numbers=off
asyncio.run(main())
}}}

rather than:

{{{#!highlight python numbers=off
loop = asyncio.get_event_loop()
try:
    loop.run_until_complete(main())
finally:
    loop.close()
}}}
