Question 1.
What function do you use to start a coroutine in asyncio?
Show hintHide hint
Think about how we initiate our main coroutine.
Question 2.
What does asyncio.gather() do?
Show hintHide hint
Consider how multiple tasks can finish at the same time.
3Question 3.
What does the event loop in asyncio do?
- Manages CPU-bound tasks
- Schedules and runs coroutines
- Handles synchronous blocking code
Show hintHide hint
Focus on its role in coroutine management.
4Question 4.
True or False: A coroutine can execute operations while waiting for I/O.
- True
- False
Show hintHide hint
Think about how I/O operations work in async.
Question 5.
Write a Python asyncio application that demonstrates handling three different I/O-bound tasks concurrently. Each task should simulate a time delay and print its progress.
Show hintHide hint
Use asyncio.gather to run multiple coroutines.
Question 6.
Explain why using asyncio for handling numerous API calls is more resource-efficient compared to traditional threading. Discuss potential pitfalls in switching from threading to asyncio.
Show hintHide hint
Consider the differences in resource allocation between threading and asyncio.
