What is the output of the following? “`python import asyncio async def fetch(n): await asyncio.sleep(0) return n * 2 async def main(): results = await asyncio.gather(fetch(1), fetch(2), fetch(3)) print(results) asyncio.run(main()) “`

What is the output of the following? “`python import asyncio async def fetch(n): await asyncio.sleep(0) return n * 2 async def main(): results = await asyncio.gather(fetch(1), fetch(2), fetch(3)) print(results) asyncio.run(main()) “`

Accepted Answer

The correct output is [2, 4, 6] because the `asyncio.gather()` function collects the results of all the `fetch()` functions and returns them in the order they were called. In this case, `fetch(1)` returns 2, `fetch(2)` returns 4, and `fetch(3)` returns 6.
