Concurrent and Parallel Programming in Python - Asynchronous Tasks

The video tutorial explains the difference between synchronous and asynchronous execution in Python, focusing on how to create and manage tasks using async IO. It demonstrates how to schedule tasks and manage their execution, highlighting the benefits of concurrent execution. The tutorial provides examples of task creation, scheduling, and execution, showing how to optimize code to run tasks simultaneously, thus improving efficiency.

What is the main reason the execution remains synchronous despite using asynchronous syntax?

• The function is not defined properly.

• The asynchronous syntax is incorrect.

• There are no other tasks to switch control to.

• The event loop is not functioning.

What is the purpose of creating tasks in the event loop?

• To simplify the syntax of asynchronous functions.

• To allow multiple tasks to be worked on while awaiting responses.

• To make the code more readable.

• To increase the speed of the event loop.

How does creating a task affect the execution time of asynchronous functions?

• It makes the execution time unpredictable.

• It decreases the execution time.

• It increases the execution time.

• It has no effect on the execution time.

What module is used to create and schedule tasks in the example provided?

• time

• asyncio

• threading

• multiprocessing

What happens when control is given back to the event loop during concurrent execution?

• The event loop resets.

• The event loop can work on other scheduled tasks.

• The event loop executes tasks sequentially.

• The event loop stops functioning.

In the context of the video, what is a coroutine?

• A module for handling asynchronous operations.

• A method for creating tasks in the event loop.

• A function that can pause and resume execution.

• A type of function that runs synchronously.

What is the benefit of having multiple coroutines running at the same time?

• It reduces the complexity of the code.

• It allows for more efficient use of resources.

• It ensures tasks are completed in order.

• It simplifies error handling.
