Getting return code for a Python script invoked from a Linux shell script
Hi, folks, I have a Python script that is invoked by a shell script. I uses sys.exit() with a parameter within python. The calling script is using this line to get the return code: exit_code = !$ but it fails to get it. What's wrong here? (I am no Linux guru) Thanks in advance Mark -- http://mail.python.org/mailman/listinfo/python-list

I presumed that absolute address somehow qualifies my question. If it is not - I was talking about physical computer memory, on PC - to be more specific. In pure Python it's not possible and even in C it might be difficult to get an absolute *physical* memory address unless you run DOS. Modern operating systems tend to use some virtualisation of memory. :-) What's your goal? What do you expect at the memory address you want to access? Ciao, Marc 'BlackJack' Rintsch My goal is to sync program with external equipment through a register defined as an absolute physical address. I know how to do it from C - was curious if it may be done from Python. Can it be done? Thanks, Mark -- http://mail.python.org/mailman/listinfo/python-list

Formatting device from a script on Windows
Hello, folks! Script I am creating has to format a device - USB flash drive. I have tried using regular DOS format through os.system - did not work well, because DOS format requires input from user. And the script should run without user interference. I have taken a look at ActivePython win32... libraries - did not find anything. Ideas? Pretty please?

How to couple pyunit with GUI?
I am desperately looking for an info how to combine a testing application with decent GUI interface - the way most xUnits do. I believe I have seen something about using Tkinter, but I do not remember - where. I am working on a complex testing application built over unittest module, and I need GUI interface that will alllow me to select tests at different levels of test hierarchy tree.
