Network-Packets
by Sunil Ghai Jan. 2, 2008

Jan. 2, 2008

Hello guys, I know this is not the right place for asking about this but i am sure some of you must have an idea about this. I have a bit knowledge about networking and protocols. I would like to know what do we actually mean by "Bandwidth". As in if a person is allowed to download stuff of about 400MB than is it the size of all the Packets the system recieves? and if by some reason the operating system discards the packet it recieves and does not forward to the appropiate application through port number then that packet size gets include in the limited access of user or not? I am really in need to get clear this point. Thanks alot in advance.. -- Sunil Kumar Ghai

Logging Help
by Robert Rawlins - Think Blue Jan. 2, 2008

Jan. 2, 2008

Hello Guys, I'm having a little trouble modifying my logging so that the log files are rotated. I'm using the standard python logging module and can find some decent documentation on how to create and add a rotatingFileHandler to my logger but I've been unable to find out how to disable the standard File handler. I currently create my logger like this: logging.basicConfig(level=logging.DEBUG, format='%(asctime)s %(levelname)-8s %(message)s', datefmt='%a, %d %b %Y %H:%M:%S', filename='/var/log/ThinkBlue.log', filemode='a') What's the best way to change this so that ThinkBlue.log grows no larger than let's say 5mb and that we keep 5 archives of the log, I know I can create a new handler and add it to the logger like this: newlevel = logging.handlers.RotatingFileHandler('/var/log/ThinkBlue.log', 'a', 5000, 5) logging.getLogger('').addHandler(newlevel) But fear this will mean I'm writing to the log file twice, is that right? I need some help, am I going about this the correct way of is there a better way of doing this? Cheers guys, Rob

PyCairo, PIL and StringIO
by Jair Trejo Jan. 2, 2008

Jan. 2, 2008

I'm doing some image processing in PIL, and I want to display the results in a GTK window using PyCairo, so I create a Cairo image surface from the PIL Image like this: mfile = StringIO.StringIO() final.save(mfile, format="PNG") ima = cairo.ImageSurface.create_from_png(mfile) mfile.close() return ima Where final is a PIL image. The problem is, I get a IOError: error while reading from Input Stream. ¿Any idea of why is this happening? I tried saving to a temporary file, i.e., replace the above code with: final.save('final.png') ima = cairo.ImageSurface.create_from_png('final.png') Instead of a StringIO object, and it works just fine. ____________________________________________________________________________________ ¡Capacidad ilimitada de almacenamiento en tu correo!

I wanted to format the text in a specific way and thought it might be quicker to output all the text to a temporary file that I could quickly read sections from instead of storing in memory. Not sure if this is the most efficient way to do this or not but thought at least it'd be a good way to learn something new in Python. I was assuming tmpfile() would automatically create some sort of temporary file that would automatically delete itself when the code was finished. -- > Try this: > >>> import os > >>> c = os.tmpfile() > >>> c.write('dude') > >>> c.seek(0) > >>> c.read() > 'dude' redawgts, thank you very much for the example!

Thank you all for sharing your knowledge of Python... this is extremely helpful to me! Jay

Tab indentions on different platforms?
by xkenneth Jan. 2, 2008

Jan. 2, 2008

All, I seem to be having problems with running my python code, written on a Mac, on Linux and Windows boxes. It seems like the problem has to do with tab indention, particularly I've noticed that my code will completely ignore try statements. Has anyone had a similar problem? Regards, Ken
