Re: [Tutor] 答复: Any book to study Python
I'm reading your book and just typeing the TCP server and client example scripts to my python and run it, but I did not get the expected results. For tstclnt.py(example 16.2,page 473 on the book),when I typed in vi and execut it by python tstclnt.py, I get the error of 'No route to host'. Of course I modified the IP address to 192.168.1.11 which is on another linux server in the script, I pinged the 192.168.1.11 and get successfully.(On 192.168.1.11 I run the TCP server program, it is the one on the book) Please see the screen shot for detail. Can you give me some suggestion on this error? hi xianming, any of the tutors here can help you, not just me! :-) instead of a screenshot (many people use only terminals to read email), it's best to just cut-n-paste the code and error traceback into your email. based on what you sent in, it would be worthwhile for you to also post the server code and output as well. note that a positive ping and the client speaking to an address are somewhat but not entirely related. the reason is that different network protocols are being used. ping uses ICMP -- http://en.wikipedia.org/wiki/Internet_Control_Message_Protocol -- while the code uses TCP -- http://en.wikipedia.org/wiki/Transmission_Control_Protocol -- instead. once you provide the server code and output, people may be able to help you better. best regards, -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - A computer never does what you want... only what you tell it. wesley chun : wescpy at gmail : @wescpy/+wescpy Python training consulting : CyberwebConsulting.com Core Python books : CorePython.com Python-flavored blog: wescpy.blogspot.com ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

But it is a very good point that install the python interepter on Windows platform and copy/paste the code in the command line to run it directly, this will avoid some type error. Thanks for your suggestion!. On this, and most forums, it's good form to put your comments *after* the part you're quoting. What you did is called top-posting, and it makes the sequence out-of-order. But the real reason i'm responding is to suggest that you can certainly cut and paste between virtual machine and host. If you cannot on your particular setup, you should get it fixed. If that's not feasible, you can always share files between the two, and do your copy/paste that way. It's hard to imagine not having such capabilities. -- DaveA ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

To Wesley, I did not realize you are the author of Python 核 心 编 程 (第二版) until I read the book's note online carefully and found your name. It's very exciting! You know this is the first time in my life that the book's author e-mail me. After I get it I shall start to read in my weekend and if there is any questions I shall write e-mail to you. Thanks again! hi xian-ming, i'm replying here to address dave angel's comment to reply *after* the email (this is called bottom-posting so that people here can see what your issue and context are. many people normally top-post or reply at the beginning, but it is not as easy to read this when communicating in a technical forum like this. i can even remove the parts of your message which i am not responding to (like i did above). about Python 核 心 编 程 (第二版) and my participation, thanks to you and Leam for your kind remarks, however i am a Python user just like everyone else here... the only difference is that i started using Python in 1997 which gives me more experience. :-) i'm also a crazy engineer that is also interested in *documentation* -- i know, i'm losing my reputation as a developer now. 8| i hope that the criticisms of the translator can be minimized (just watch out for the bad code indentation), and that they were able to interpret what i really wanted to say, otherwise you may have to find the English one. i try to use easy-to-understand English, so it should not be *too* bad. anyway, if you have more questions, please cut-n-paste your code here along with the output, and everyone can help you more effectively. 谢谢! -- wesley - 陈仲才 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - A computer never does what you want... only what you tell it. wesley chun : wescpy at gmail : @wescpy http://twitter.com/wescpy/ +wescpy http://plus.ly/wescpy Python training consulting : CyberwebConsulting.com Core Python books : CorePython.com http://corepython.com/ Python-flavored blog: wescpy.blogspot.com ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
