Licence & Why These Books Are FreeElena Daehnhardt |
A quick overview
The books published on this website are shared freely to support learning, curiosity, and confidence in Python, Artificial Intelligence, and related topics.
They are written for beginners of all ages — especially children, parents, teachers, and anyone who prefers calm, clear explanations over hype.
Why these books are free
I believe that access to learning should not depend on budgets, subscriptions, or gatekeeping.
These books are free because:
- learning works best when curiosity comes first
- parents and teachers should be able to share resources easily
- beginners deserve a gentle, welcoming entry point
- knowledge grows when it is shared responsibly
If you choose to support the work financially (for example, via “pay what you want”), you are helping fund future books, courses, and free learning materials — but payment is never required to read or learn.
