While some of the complaints are valid others simply reflect the time and place. I believe Mr Pilgrim has taken the conscious decision to have the web site mirror his book, so changing it would leave them out of synch. Similarly, I assume the book was a one-off project and he has no desire to revisit it. (Or maybe his publisher has no desire, it's not all in the author's control!) I took the alternative view that the book was a snapshot of my web site and the web site continues to evolve while the book is frozen in 1999. But both approaches are valid and Pilgrim's book still has much to teach, although it's definitely not for beginners and it's not one of my personal favourites. But if the style fits the reader I certainly wouldn't discourage its use. My own book took just short of 2 years to put together (and it already existed as a web site so I had the basic structure and words in place), updating a book is a significant commitment. Even updating my web site to Python v3 has taken me about 18 months so far and I'm only 70% through it... If you are not a full time author and it's not a primary revenue source it takes more than a change in technology to motivate a rewrite!

Alan Gauld alan.ga...@btinternet.com wrote Learn Python the Hard Way: http://learnpythonthehardway.com/index These were both new ones to me, thanks for sharing! I've just finished skimming this one and its pretty good IMHO! My only gripe is the final chapter - Advice from an old programmer. It seems Mr Shaw has become somewhat disillusioned with the software engineering profession, but as someone who has beenn programming for at least as long as he has I have to say that I still enjoy it and find it rewarding both personally and financially. So don't let the final page of cynicism put you off a career in software engineering. Otherwise, if you are looking for a newbie tutorial this a is a good one although it has less depth than most other tutors, it's still a good first step. I assume it's still a work in progress too, since it jumps from Exercise (aka chapter) 10 to Excercise 27 in one go!

[Tutor] reading binary file on windows and linux
Hello, I've got some trouble reading binary files with struct.unpack on windows. According to the documentation of the binary file's content, at the beginning there're some simple bytes (labeled as 'UChar: 8-bit unsigned byte'). Within those bytes there's a sequence to check the file's sanity. The sequence is (in ascii C-Notation): \n \r \n I've downloaded the file from the same website from two machines. One is a Windows 7 64-Bit, the other one is a virtual Linux machine. Now the trouble is while on linux everything is fine, on windows the carriage return does not appear when reading the file with struct.unpack. The file sizes on Linux and Windows are exaktly the same, and also my script determines the file sizes correctly on both plattforms (according to the OS). When I open the file on Windows in an editor and display the whitespaces, the linefeed and cariage-return are shown a expected. The code I'm using to check the first 80 bytes of the file is: import struct import sys with open(sys.argv[1]) as source: size = struct.calcsize(80B) raw_data = struct.unpack(80B, source.read(size)) for i, data in enumerate(raw_data): print i, data, chr(data) source.seek(0, 2) print source.tell() Any suggestions are highly appreciated.

Cheers, Jan I'd guess that it's because newline in windows is /r/n and in linux it's just /n. If you read the file as binary rather than text then it should work the same on both platforms ie use: open(sys.argv[1], rb) HTH, Adam. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

In windows, that representation is \r\n, meaning that that sequence is converted to just \n when you read from the file. That is why the carriage return disappears.

In text mode, whatever char seq is used by a given OS with the sense of line separator (\r\n' under win) is silently converted by python to a canonical code made of the single '\n' (char #0xa). So that, in your case, in the header sub-sequence '\r'+'\n' you lose '\r'. In so-called bynary mode 'b' instead, python does not perform this replacement anymore, so that you get the raw byte sequence. Hope I'm right on this and it helps.

Re: [Tutor] An interesting situation befalls me
It is interesting to note war against 'Dive into Python'. Personally I felt it was good, a quick resource to learn without buying O'reilly books. After I came across Alan Gauld and Mark Lutz's books, I never referred DintoP. I still have the printed version of this book from 2002-3 I guess. After a variety of circus maneuvers, I came to the following conclusion: 1. Go to http://www.freenetpages.co.uk/hp/alan.gauld/ Alan Gauld's book is a wonder. He feeds the basics right into your brain. 2. With Alan's book as basic I bought Mark Lutz's Learning Python. 3. Make use of tutors list. I owe a lot to people here like Alan and Kent Johnson. In no time, you can be a good programmer. this is my personal opinion and nothing to do with Zed's war on DintoP.
