Problem

Implement a function that takes in a list of numbers and an asynchronous function, and returns a list of the results of the function applied to each number in the list.
Input: [1, 2, 3], async_func
Output: [async_func(1), async_func(2), async_func(3)]

Solution

import asyncio

async def async_func(x):
    await asyncio.sleep(1)
    return x

async def main():
    l = [1, 2, 3]
    tasks = [async_func(x) for x in l]
    results = await asyncio.gather(*tasks)
    print(results)

asyncio.run(main())
