It's well written, the concepts are well explained with self evident examples. A great guide with great examples. Awesome work. And that too for free. Highly recommended for aspiring pythonistas.
Probably the best to start with, and probably the best in the world for every newbie or even a more experienced user. I just started learning how to code two days ago and I'm already building some simple games.
Your guide has been a dream and I just wanted to let you know how valuable it has been. Firstly i want to say that your book "The byte of python" is too good a book for a beginner in python like me.
It is one of the best written and easy to follow programming books I have ever read. Congratulations and keep up the great work. I learnt much from all the examples. Your book is of great help for newbies like me The book is very simple but can help all the first learnners.
You know I am interesting in Java and cloud computing many times, i have to coding programm for the server, so i think python is a good choice, finish your book, i think its not only a good choice its must use the Python. My English is not very well, the email to you, i just wanna thank you! Best Wishes for you and your family. I was very sad to reach the final pages as I now have to go back to dull, tedious oreilly or etc.
Anyway, I really appreciate your book. Samuel Young Dear Swaroop, I am taking a class from an instructor that has no interest in teaching.
We are using Learning Python, second edition, by O'Reilly. It is not a text for beginner without any programming knowledge, and an instructor that should be working in another field. Thank you very much for your book, without it I would be clueless about Python and programming. Thanks a million, you are able to break the message down to a level that beginners can understand and not everyone can. It is the greatest Python tutorial ever, and a very useful reference.
Brilliant, a true masterpiece!
Keep up the good work! I think it is a good book for those who are looking for a beginner's tutorial for Python. It is about two or there years ago, I think, when I first heard of this book.
At that time, I am not able to read some book in English yet, so I got a chinese translation, which took me into the gate of Python programming. Recently, I reread this book. This time, of course, the english version. I couldn't believe that I can read the whole book without my dictionary at hand.
Of course, it all dues to your effort to make this book an easy-to-understand one. I had been attempting Python for a few months prior to stumbling across your book, and although I made limited success with pyGame, I never completed a program. While you are working on these projects, you can continue to refer to the chapters in this book as reference material. Anyone who learns how to code can contribute to an open-source project. Open-source software is software that is freely available to use, redistribute, and modify.
Contributing to open-source projects helps improve software by ensuring that it is representative of the broad base of technology end-users. When users contribute to open-source projects through code, technical documentation, or repository maintenance, their diverse perspectives provide added value to the project and the larger developer community.
According to the EPUB specification, the identifier must be a unique value, although it's up to the digital book creator to define that unique value.
Note that the value of the attribute unique-identifier must match the ID attribute of the dc:identifier element. Other metadata to consider adding, if it's relevant to your content, include: Language as dc:language. Publication date as dc:date. Publisher as dc:publisher. This can be your company or individual name. Copyright information as dc:rights. Including a meta element with the name attribute containing cover is not part of the EPUB specification directly, but is a recommended way to make cover pages and images more portable.
This example shows both forms. The value of the meta element's content attribute should be the ID of the book's cover image in the manifest, which is the next part of the OPF file. This usually means a list of XHTML files that make up the text of the eBook plus some number of related media such as images. Every file that goes into your digital book must be listed in the manifest. Listing 5 shows the extracted manifest section.
Listing 5. Extract of OPF manifest You must include the first item, toc. You can include non-supported file types if you provide a fall-back to a core type. See the OPF specification for more information on fall-back items. This is easy to confuse with the reference to the OPF file in the container. Spine Although the manifest tells the EPUB reader which files are part of the archive, the spine indicates the order in which they appear, or—in EPUB terms—the linear reading order of the digital book.
One way to think of the OPF spine is that it defines the order of the "pages" of the book. The spine is read in document order, from top to bottom. Listing 6 shows an extract from the OPF file. Listing 6. Extract of OPF spine Each itemref element has a required attribute idref, which must match one of the IDs in the manifest.
The toc attribute is also required. The linear attribute in the spine indicates whether the item is considered part of the linear reading order versus being extraneous front- or end-matter. Guide The last part of the OPF content file is the guide.
This section is optional but recommended. Listing 7 shows an extract from a guide file. Listing 7. Extract of an OPF guide The guide is a way of providing semantic information to an EPUB reading system. While the manifest defines the physical resources in the EPUB and the spine provides information about their order, the guide explains what the sections mean.
Here's a partial list of the values that are allowed in the OPF guide: cover: The book cover title-page: A page with author and publisher information toc: The table of contents For a complete list, see the OPF 2. This is rarely a problem when you generate EPUBs programmatically, where the same code can output to two different files.
Take care to put the same information in both places, as different EPUB readers might use the values from one or the other. Although the OCF file is defined as part of EPUB itself, the last major metadata file is borrowed from a different digital book standard.
DAISY is a consortium that develops data formats for readers who are unable to use traditional books, often because of visual impairments or the inability to manipulate printed works. The NCX defines the table of contents of the digital book. In complex books, it is typically hierarchical, containing nested parts, chapters, and sections.
Listing 8. This element should match the dc:identifier in the OPF file. This example has only one level, so this value is 1.
It's okay to be confused, as both files describe the order and contents of the document. The easiest way to explain the difference is through analogy with a printed book: The OPF spine describes how the sections of the book are physically bound together, such that turning a page at the end of one chapter reveals the first page of the second chapter.
The NCX describes the table of contents at the beginning of the book. The table of contents always includes all the major sections of the book, but it might also list sub-sections that don't occur on their own pages.
The navMap is the most important part of the NCX file, as it defines the table of contents for the actual book.
The navMap contains one or more navPoint elements. Each navPoint must contain the following elements: A playOrder attribute, which reflects the reading order of the document.
This follows the same order as the list of itemref elements in the OPF spine. This is typically a chapter title or number, such as "Chapter One," or—as in this example—"Cover page. This will be a file declared in the OPF manifest. It is also acceptable to use fragment identifiers here to point to anchors within XHTML content—for example, content.
