Re: help
For such a simple task, I would use MATLAB. http://www.mathworks.com/products/matlab/ However, if you have to do generic programming in addition to this, I would use Python with the libraries ImageMagick or Python Image Library (PIL). Just search for them and you'll have all the examples you need. -- http://mail.python.org/mailman/listinfo/python-list
Re: How could I ask Thread B to call B().Method() from inside Thread A's run?
I agree with jmj's solution, you would want to send a signal of some sort to Thread B from A when some event occurs in A. A queue is one way to do it, but keep in mind that there are numerous ways to communicate between threads/processes (queue, pipe, exit status, TCP/UDP message, etc.). I believe one of the first couple chapters in O'Reilly's "Programming Python" book discusses most of these methods. Choose the simplest one that meets your needs. -- http://mail.python.org/mailman/listinfo/python-list
Re: Automate decryption using GnuPGInterface
Are you able to run a dummy Python script using crontabs? For troubleshooting purposes, I would verify this before trying to debug my code. Check your permissions, paths, etc. Can you post your entry into cron? What exactly happens when it "blows up"? -- http://mail.python.org/mailman/listinfo/python-list
Re: XML processing
I haven't used PyXML extensively, but I have used parts of the Amara XML Toolkit (http://uche.ogbuji.net/uche.ogbuji.net/tech/4suite/amara/) and recommend it for elegance. I can't say, however, which tool is faster. There are many other XML modules that people have written for Python. Do your research and pick the best one for you. On a side note, XML has historically been a poor solution for most of the cases I've seen it used. You should seriously rethink whether you "need to do some XML programming" and consider simpler options. In most simple cases, a primitive text parser with a delimited format is your best bet. You would know best, but this is my 2 cents. -- http://mail.python.org/mailman/listinfo/python-list

Re: __init__ method and raising exceptions
Or better yet, define your own string/class exception to catch your errors. In my code, things can break in more than a few ways. In each case I catch the exception(s) specific to that piece of code, print a warning message to the user at sys.stdout and raise a new exception to be caught by my "wrapper" exception clause. -- http://mail.python.org/mailman/listinfo/python-list
Re: __init__ method and raising exceptions
Exactly the answer I was looking for! 12 hours of straight programming tends to fog ones mind. Thanks for making it clear! Jay -- http://mail.python.org/mailman/listinfo/python-list
__init__ method and raising exceptions
I have a simple for-loop, which instantiates a class object each iteration. As part of my class constructor, __init__(), I check for valid input settings. If there is a problem with this iteration, I want to abort the loop, but equivalently 'continue' on in the for-loop. I can't use 'break' or 'continue' in a class method, nor can I return a boolean value from __init__() to check for errors within the for-loop. How would I be able to stop the current iteration and continue with the next after reporting an error? Jay -- http://mail.python.org/mailman/listinfo/python-list
