Asyncio Basics

Main idea

Async tasks cooperate via event loop and await points.

Tip

Use await on async operations only.

Watch out

Blocking calls inside async function.

Asyncio Basics is used in many real programs. Right now you are in Advanced Engineering.

Core idea:
Async tasks cooperate via event loop and await points.

Read the example code on this page. Then write your own short version.

Tip:
Use await on async operations only.

Watch out for:
Blocking calls inside async function.

Your challenge:
Async task scheduler with sleep simulation.

Use the editor in the challenge lab. When your output looks correct and there is no error, press the green button to unlock the next topic.

Example code

Copy this example if it helps. Change it so it matches Asyncio Basics.

# Topic: Asyncio Basics
def main():
    sample = "edit me"
    # TODO: apply Asyncio Basics concept here
    result = sample
    print("Result:", result)

if __name__ == "__main__":
    main()

Challenge

Async task scheduler with sleep simulation.

Before you can finish: your output should include at least 16 characters; at least 1 non-empty line(s); no crash traceback—fix errors until the program runs cleanly.

Use Run. Read the output. Change your code until the task is done.

Starter reference

# Challenge starter for Asyncio Basics
def solve():
    # Write your solution here
    pass

print("Update solve() and run")

Your code

The first Run may load Python in your browser (one-time). Later runs are faster.
