Dictionary to tree format (hopefully simple)

Re: Confused: appending to a list

You're wanting it to stop when the len(list) == 4, right? The easiest way to change the logic would be to say while len(list) != 4: but that could get you into trouble later on. The problem with the len(list) < 5 expression is that the loop will run "one more time" as long as len(list)

Re: Interrput a thread

ther, I'm not entirely convinced of the utility. Only allowing the exception to be thrown from defined cancellation points is much better (ala POSIX threads), but diminishes the utility for things that are mostly grinding away in userspace.

Re: os.path.realpath() and os.path.abspath()

ensures that is the case. Historically, some versions of the UNIX syscall (Solaris in particular) have not always returned absolute paths, but I believe this is no longer the case and was a very long standing bug (though I may be mistaken).

Perhaps, but the drop off isn't relevant till we approach well over 30 widgets, at least, quite arguably more (since GUI toolkits include both things that are common, and things that absolutely suck to program, even if they're not used often).

Re: examples of realistic multiprocessing usage?

Re: examples of realistic multiprocessing usage?

oid contention between two queues is to just remove it entirely (by converting the processing to a single pipeline like I suggested). If that is not possible, then I suggest moving to pipes (or some other form of I/O based IPC) and asynchronous I/O. But I'd only do that if I really couldn&#

Re: examples of realistic multiprocessing usage?

ue is the superior solution. It's certainly possible to build a work pool w/ a queue such that you block on both for entries added to the queue and job completion, but I'm pretty sure it's something you'd have to write yourself. Adam -- http://mail.python.org/mailman/listinfo/python-list
