Frequently Asked Questions

We no longer require registration to access the code examples or other online resources for our books on the new deitel.com. 

Each book’s webpage has a link to our GitHub repository where you can download the code for our most recent books. If you do not use GitHub, each book’s webpage also provides a link that allows you to download from GitHub a ZIP file containing the examples.

For older How to Program books, some downloads are still available via our publisher’s Deitel site. Check out our Other Books page for direct links to many edition’s examples.

If you’re having trouble finding a download, please contact us.

If you have one of our How to Program Series books or our book Intro to Python for Computer Science and Data Science, you do not need the “for Programmers” book. Each is a subset of the corresponding textbook.

Our “for Programmers” books generally are geared to programmers moving from one programming language to another. 

Unlike our textbooks, our “for Programmers” books do not have:

• Self-check exercises with answers
• End-of-chapter exercises
• Low-end pedagogical explanations that teach novice programming fundamentals

Intructors: Unlike our textbooks, our Deitel Developer Series “for Programmers” books are not supported by instructor supplements, such as lecture slides, test-item files and instructor solutions manuals. 

If you have one of our “for Programmers” books, you don’t need textbook.

Many professionals prefer our textbooks, particularly due to their extensive end-of-chapter exercises, which enable professionals to practice what they’ve learned.

Note that the exercise solutions are available only to instructors teaching college courses from the textbooks. 

Please contact us with your questions and we’ll respond promptly.
