150+ Interview Questions
(and answers) on Python Asyncio
Challenge Your Knowledge of the Asyncio API in Python
Discover pointed interview questions (and answers) allowing you to learn the asyncio API.
Also invaluable for preparing for a job interview and evaluating candidates.
How well do you know Python Asyncio?
Python includes changes to the language itself to support coroutines as first-class objects and the asyncio module provides an API for developing asynchronous programs.
Asyncio is challenging to learn for beginners and challenging to use for experts and beginners alike.
Asynchronous programming is an alternative paradigm that is quite different from the classical imperative and object-oriented programming paradigms that we are useful.
- Do you know how to cancel an asynchronous task?
- Do you know how to execute a list of coroutines concurrently?
- Do you know how to execute blocking calls in an asyncio program?
Discover 150+ interview questions and their answers on Python asyncio.
- Study the questions and answers and improve your skill.
- Test yourself to see what you really know, and what you don’t.
- Select questions to interview developers on a new role.
Prepare for an interview or test your asyncio and coroutine skills in Python today.
- 150+ questions to prepare you and test your knowledge of the API.
- 17 sections covering all aspects of the API, including functions and classes.
- 83 pages for on-screen reading open next to your editor.
- 2 formats (PDF and EPUB) for screen, tablet, and kindle reading.
- zip download that contains both formats of the ebook.
This book provides a large number of questions on what, how, and when to use the Python asyncio API.

Frequently Asked Questions
This section covers some frequently asked questions.
If you have any questions. Contact me directly. Any time about anything. I will do my best to help.
What version of python do you need?
All code examples use Python 3.
Python 3.9+ to be exact.
Python 2.7 is not supported because it reached its “end of life” in 2020.
What format is the book?
You can read the book on your screen, next to your editor.
You can also read the book on your tablet, away from your workstation.
The ebook is provided in 2 formats:
- PDF (.pdf): perfect for reading on the screen or tablet.
- EPUB (.epub): perfect for reading on a tablet with a Kindle or iBooks app.
Many developers like to read technical books on their tablet or iPad.
How can you get more help?
The sections in this book were designed to be easy to read and follow.
Nevertheless, sometimes we need a little extra help.
A list of further reading resources is provided at the end of each section. These can be helpful if you are interested in learning more about the topic covered, such as fine-grained details of the standard library and API functions used.
If you ever have questions about the lessons or code in this book, you can contact me any time and I will do my best to help. My contact details are provided at the end of the book.
How many pages is the book?
The PDF is 83 US letter-sized pages.
Can you print the book?
Although, I think it’s better to work through it on the screen.
- You can search, skip, and jump around really fast.
- You can copy and paste code examples.
- You can compare code output directly.
Is there digital rights management?
The ebooks have no DRM.
Do you get free updates?
Each time I release an updated version, I will send you an email with a link so that you can download the latest version for free.
You can also email me any time and I will send you the latest version.
Can you buy the book elsewhere?
In fact, the book was the #1 new release in its category shortly after its release.
Can you read a sample?
You can read a book sample via google books “preview or via the amazon “look inside” feature:
About the Author
Hi, I’m Jason Brownlee, Ph.D.
I’m a Python developer, husband, and father to two boys.
I want to share something with you.
I am obsessed with Python concurrency, but I wasn’t always this way.
My background is in Artificial Intelligence and I have a few fancy degrees and past job titles to prove it.

Well, AI and machine learning has been hot for the last decade. I have spent that time as a Python machine learning developer:
- Working on a range of predictive modeling projects.
- Writing more than 1,000+ tutorials.
- Authoring over 20+ books.
There’s one thing about machine learning in Python, your code must be fast.
Modeling code is already generally fast, built on top of C and Fortran code libraries.
But you know how it is on real projects…
You always have to glue bits together, wrap the fast code and run it many times, and so on.
Making code run fast requires Python concurrency and I have spent most of the last decade using all the different types of Python concurrency available.
Including threading, multiprocessing, asyncio, and the suite of popular libraries.
I know my way around Python concurrency and I am deeply frustrated at the bad wrap it has.
This is why I started SuperFastPython.com where you can find hundreds of free tutorials on Python concurrency.
And this is why I wrote this book.
Praise for Super Fast Python
Python developers write to me all the time and let me know how helpful my tutorials and books have been.
