3 cards from this section. Quick, good the night before a test.
What is asynchronous programming?
Think about how tasks can proceed at the same time.
What are coroutines in Python?
Remember, they are defined with 'async def'.
What keyword is used to define a coroutine in Python?
Think about how we create functions in Python and which keyword is different.
True or False: Coroutines in asyncio must always be awaited.
Remember, await is essential for coroutines to function!
Create a Python script that simulates fetching data from three different APIs concurrently using asyncio. Structure your code using coroutines and handle all responses in a single main function.
Think about how each API call would take time and should be executed in the background while you prepare the print statement.
Write a program that manages multiple file reads using asyncio, ensuring no 'blocking' occurs when waiting on I/O operations. Include error handling for file absence.
Consider how to structure your function calls to wait for multiple files to be read while ensuring any missing files are properly caught.
