Modules Modules You have seen how you can reuse code in your program by defining functions once. What if you wanted to reuse a number of functions in other programs that you write? As you might have guessed, the answer is modules. There are various methods of writing modules, but the simplest way is to create a file with a. Another method is to write the modules in the native language in which the Python interpreter itself was written.

It serves as a tutorial or guide to the Python language for a beginner audience. If all you know about computers is how to save text files, then this is the book for you. For Python version 3 This book will teach you to use Python version 3. There will also be guidance for you to adapt to the older and more common Python version 2 in the book.
Who reads A Byte of Python? Here are what people are saying about the book: This is the book that got me into programming almost a decade ago.
Thank you swaroopch. You changed my life. It was a really good book that I enjoyed thoroughly. But I felt like your book gave was much easier to understand and eased me into the whole new world of programming.
Thanks to you, I can now write a high level language with ease. I would like to thank you again for your hard work on helping out beginners like me. Thank you for your effort. 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.
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. 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! 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. 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. Thanks to your simplification of the categories, Python actually seems a reachable goal. It seems like I have finally learned the foundations and I can continue into my real goal, game development.
Once again, thanks VERY much for placing such a structured and helpful guide to basic programming on the web. It shoved me into and out of OOP with an understanding where two text books had failed. I am a 15 year old i live in egypt my name is Ahmed.
I made the addressbook program and i was sucessful. I will also start on learning java and if you can tell me where to find a tutorial as good as yours for java that would help me a lot. It is well-written, easy to follow, and may be the best introduction to Python programming available. Highly recommended as a starting point for learning Python. Excellent reads FeelGoodFactor -- Surendran "Byte of python" best one by far man in response to the question "Can anyone suggest a good, inexpensive resource for learning the basics of Python?
Thanks bigtime : Chinmay Always been a fan of A Byte of Python - made for both new and experienced programmers. This book written by Mr. Swaroop is a very good guide for both brand-new programmers and new python programmers. Took 10 half days to go through it. Great Help! This book cleared up many questions I had about certain aspects of Python such as object oriented programming.
I do not feel like an expert at OO but I know this book helped me on a first step or two. I have now written several python programs that actually do real things for me as a system administrator. They are all procedural oriented but they are small by most peoples standards. Again, thanks for this book. Thank you for having it on the web. Python is now my first language, and I can just imagine all the possibilities.
So thank you for giving me the tools to create things I never would have imagined I could do before. Needless to say, I am a beginner in the programming world, a couple of months of self study up to this point. Thank you so much for not only writing the book, but for putting it under the creative commons license free.
Without it, I would have fallen by the wayside. Since then I have gone on to program a number of functions in my organization with this language with yet more on the horizon. I would not call myself an advanced programmer by any stretch but I notice the occasional request for assistance now from others since I started using it.
Of course, there was no explanation for this arrangement of operators and I fell on my head trying to make sense of what was on the written page. As I recall it was a most frustrating exercise which I eventually abandoned. Just as computers will not be able to understand a computer word or computer symbol that is outside the syntax for the language being used, a student new to any field will not grasp his subject if he encounters words or symbols for which there are no definitions.
You get a "blue screen" as it were in either case. The solution is simple, though: find the word or symbol and get the proper definition or symbol and lo and behold,the computer or student can proceed.
So, thank you. I encourage you to continue to include full definitions of terms. The documentation with Python is good, once you know, the examples are its strength from what I see but in many cases it seems that you have to know in order to understand the documentation which to my mind is not what should be.
Third party tutorials express the need for clarification of the documentation and their success largely depends on the words that are used to describe the terminology. I have recommended your book to many others. Some in Australia, some in the Caribbean and yet others in the US. It fills a niche no others do. I hope you are doing well and wish you all the success in the future. I was facing a great difficulty to start with python.
I tried a lot of books but all were bulkier and not target oriented; and then i found this lovely one, which made me love python in no time. Thanks a lot for this "beautiful piece of book". I am a molecular biologist with little programming background and for my work I need to handle big datasets of DNA sequences and to analyse microscope images.
For both things, programming in python has been useful, if not essential to complete and publish a 6-years project. That such a guide is freely available is a clear sign that the forces of evil are not yet ruling the world!
It really gives a proper introduction into programming in Python and it is paced well enough for the average beginner. The most important thing from then on will be actually starting to practice making your own little programs. Those books were very useful to me four or five years ago when I starting learning programming.
Keep walking. You are a source of motivation. All the best.
