Challenge: Asynchronous Programming

Test your knowledge of using asynchronous generators to improve your code.

We'll cover the following


Refactor the program below, which processes a large amount of data synchronously. You should utilize asynchronous programming to improve the processing time.


There are two functions, process_data and process_item, on lines 4 and 9 respectively that are used to process the data set. The entire dataset is passed to process_data, which processes each item in the dataset using process_item. Within process_item, time.sleep(1) is used on line 5 to simulate a function that has a large processing time.

Refactor the code below using the asyncio library to optimize the execution time.
