The learning objectives of this project are:

• How to write an asynchronous generator
• How to use async comprehensions
• How to type-annotate generators

Write a coroutine called async_generator that takes no arguments.

The coroutine will loop 10 times, each time asynchronously wait 1 second, then yield a random number between 0 and 10. Use the random module.

Import async_generator from the previous task and then write a coroutine called async_comprehension that takes no arguments.

The coroutine will collect 10 random numbers using an async comprehensing over async_generator, then return the 10 random numbers.

Import async_comprehension from the previous file and write a measure_runtime coroutine that will execute async_comprehension four times in parallel using asyncio.gather.

measure_runtime should measure the total runtime and return it.

Notice that the total runtime is roughly 10 seconds, explain it to yourself.
