Not necessarily. The “$39.99 value—FREE for a Limited Time” claim referred to a Java Code Geeks promotion published on April 27, 2024. It does not prove that a free copy is available now. Packt and O’Reilly pages show a “free PDF copy” section, but the available listing information does not establish today’s eligibility rules, account requirements, regional limits, or whether the download is unrestricted.
What book is this?
Principles of Data Science – Third Edition is Sinan Ozdemir’s English-language data-science book from Packt. Publisher metadata dates this edition to January 31, 2024. The paperback record lists 326 pages and ISBN 9781837636303. Check those details before purchasing because retailers can mix editions and formats.
Is the book currently free?
The evidence supports a historical free promotion, not a current free-offer claim. A Java Code Geeks article dated April 27, 2024 used the headline “Principles of Data Science – Third Edition ($39.99 Value) FREE for a Limited Time.” “Limited time” means the promotion could expire, and the stated $39.99 is not a verified current price.

How to check for a legitimate free copy
- Open the current Packt page for the exact title and confirm that it says Third Edition.
- Read the text around the “Download a free PDF copy of this book” section, including any sign-in, subscription, trial, geographic, or promotional conditions.
- Verify that the download or reader view identifies Sinan Ozdemir, Packt, the 2024 third edition, and ISBN 9781837636303 where an ISBN is shown.
- If using O’Reilly, distinguish catalog access included with a subscription from a permanently free download. Check the subscription’s trial, renewal, and cancellation terms before entering payment details.
- Avoid pages that promise a free file but do not identify the publisher, edition, or a legitimate retailer/platform. Do not treat the old $39.99 headline as proof of a live deal.
Access routes and what is established
| Route | What the available evidence shows | What you must verify |
|---|---|---|
| Packt publisher page | A free-PDF-copy section is displayed for the title. | Whether the copy is currently downloadable, whether an account or subscription is required, and any regional or promotional restrictions. |
| O’Reilly catalog | The title appears in the catalog, with a free-PDF-copy section and subscription-access context. | Whether access is included in your subscription, whether a trial applies, and whether the offer is a download or online reading only. |
| Historical promotion | Java Code Geeks described a limited-time free ebook promotion on April 27, 2024 and stated a $39.99 value. | Nothing about this listing establishes that the promotion remains active. |
| Paperback purchase | Barnes & Noble lists a 326-page paperback with ISBN 9781837636303. | Current price, stock, seller, shipping, region, and exact edition at checkout. |
What you will learn
The book is organized as a progression from fundamentals to applied machine learning:
- Data-science terminology, data types, and a five-step workflow
- Basic mathematics, probability, statistics, and data communication
- Machine-learning essentials and tree-based prediction
- Transfer learning and pretrained models
- Algorithmic bias, model and data drift, and AI governance
- Real-world case studies that connect concepts to practical work
The listing says that familiarity with Python will improve the learning experience. You can still use the book for conceptual study without advanced programming, but readers should not interpret it as a professional qualification or a guarantee of job readiness.
Who should read it?
Good fit for beginners moving toward applied work
The combined treatment of terminology, math, statistics, coding-oriented workflow, machine learning, and responsible-AI topics makes the third edition suitable for beginners and intermediate readers who want one structured introduction.

- Daily Lesson Plan
- Breakdown of the assignments, detailing exactly what needs to be done each day
- Pages where the student takes notes; these pages include prompts to help teach the student how to pull out pertinent information from the text
- Space to answer the On Your Own questions that are listed in each module; these questions serve as review and prep for the tests
- Space to record their results from the many hands-on activities
Before you download or buy
- Match the title, author, publisher, edition, and ISBN to 9781837636303.
- Check whether the file is a complete PDF, a preview, or online-only reading access.
- Review account, trial, renewal, and regional terms before accepting an offer.
- Confirm the final price and format at checkout; the historical $39.99 figure is not a current quote.
The Bottom Line
Bottom line: Treat “free” as unconfirmed today. The $39.99 claim belongs to a time-limited April 2024 promotion, while Packt and O’Reilly show free-copy sections whose current terms must be checked on their live pages. For the matching book, verify the 2024 third edition and ISBN 9781837636303.
