pygresql - bytea
by Jan Danielsson May 7, 2006

May 7, 2006

Hello all, I'm trying to use pygresql to insert binary data (type: bytea) into a column (using postgresql, obviously). To make a long story short: I can't get it to work. Not even by cutting and pasting the very few examples I have found on the 'net. Does _anyone_ have a working example? A simple insertion, and a simple select is all I'm looking for. -- Kind Regards, Jan Danielsson Te audire non possum. Musa sapientum fixa est in aure.

wxPython problem
by scottholdensmith＠gmail.com May 7, 2006

May 7, 2006

I'm a little confused. I installed wxPython on my Thinkpad T23, on which I'm running Fedora Core 5. I did it using Yum and Yumex, and everything installed fine. In fact, I now have PyShell and PyCrust in my applications. Within those two apps I can use wx as a module. But from the bash shell, when I use the same old Python interpreter, I can't use the wx module. It's there, under /usr/lib/python2.4/site-packages/wx-2.6-gtk2-unicode/ (under that directory there are several directories: wx, wxPython). I don't know what to do now. Do I need to move the wx directory up directly under the site-packages directory? Please help, thanks...

String Exceptions (PEP 352)
by Thomas Guettler May 5, 2006

May 5, 2006

Hi, I like python because it is compatible to old versions. That's way I think string exceptions should not be deprecated. I use string exceptions if the condition for an assertion is to complex: if foo and bar and i>10: raise "if foo and bar i must not be greater than 10" This way I can easily add "checkpoints" to my code. Is it too late to change this? Way not make this line raise "..." behave like this: raise Exception("...") in the future? I know that catching string exceptions and reading the string is different from Exception("..."). This could become deprecated. Please keep Python compatible to old versions.

symbolic links, aliases, cls clear
by mp May 3, 2006

May 3, 2006

i have a python program which attempts to call 'cls' but fails: sh: line 1: cls: command not found i tried creating an alias from cls to clear in .profile, .cshrc, and /etc/profile, but none of these options seem to work. my conclusion is that a python program that is executing does not use the shell (because it does not recognize shell aliases). is this correct? should i use a symbolic link? if so, where should i place it? what is the difference between aliases and symbolic links? if i execute a command like 'clear' to clear the screen, where does the shell look to find the command 'clear'? i'm using os x. thanks mp

recognize a drive as removable media (e.g. compact flash, sd card or usb drive)
by Mike Joyce May 3, 2006

May 3, 2006

I am trying to write a portable script that will find removable media, such as compact flash, sd card, usb, etc. drive and then upload files from the media. I want this to be portable so that I can write and maintain one program for both Linux and Windows. Each platform uses different functions so even if I could find two platform dependent functions that would be fine. Basically, I would like to avoid checking fixed disks if possible. If anyone know of a good way to do this please let me know. Thanks in advance for any help. -Mike Joyce

Just a guess: try a new size argument that is multiple of page size.

bug in modulus?
by jantod＠gmail.com May 2, 2006

May 2, 2006

I think there might be something wrong with the implementation of modulus. Negative float values close to 0.0 break the identity "0 <= abs(a % b) < abs(b)". print 0.0 % 2.0 # => 0.0 print -1e-010 % 2.0 # =>1.9999999999 which is correct, but: print -1e-050 % 2.0 # => 2.0 print -1e-050 % 2.0 < 2.0 # => False This means I can't use modulus to "wrap around" before it reaches a certain value. I'm using Python 2.4.2 on WindowsXP. Thanks Janto
