In PyQt you can do something like the following to allow the user to select a file filename = QtGui.QFileDialog.getOpenFileName(self, "Choose file..") However I would like a QFileDialog to open in which the user would be able to select either a file or a directory. I'm sure I've seen this feature in PyQt applications before, but I can...
I have a Pylons controller action that needs to return a file to the client. (The file is outside the web root, so I can't just link directly to it.) The simplest way is, of course, this: with open(filepath, 'rb') as f: response.write(f.read()) That works, but it's obviously inefficient for large files. What's the best way...

Would it be possible to integrate Python (and/or Perl) and Ruby? I've looked at http://www.goto.info.waseda.ac.jp/~fukusima/ruby/python/doc/ and http://code.google.com/p/ruby-perl/ , but they both seem rather outdated. Has someone generated a Ruby interface for Python's C API? Edit: Python can be integrated with many other languages ac...
I'm looking into releasing a python package which includes an existing fortran or C program. The fortran/C program is compiled by running ./configure make The python code calls the resulting binary through subprocess calls (i.e. the code is not really wrapped as such). What I would like is that when the user types python setup.py ins...

Suppose my model is this: class Ego(models.Model): event = models.ForeignKey(Event) user = models.ForeignKey(User) As you can see, this table has 2 columns, and they're both foreign keys. How do I "order by" User.first_name? Is this it? But it doesn't look like it. Ego.objects.all().order_by("User.first_name") ...
Hi I have an XML (in the form of tree), I require to create sub-tree out of it. For ex: <a> <b> <c>Hello</c> <d> <e>Hi</e> </a> Subtree would be <root> <a> <b> <c>Hello</c> </b> </a> <a> <d> <e>Hi</e> </d> </a> </root> What is the best XML library in python to do it? Any algorithm that already does...

I have a simple .exe that needs to be running continuously. Unfortunately, sometimes it crashes unexpectedly, and there's nothing that can be done for this. I'm thinking of like a C# program that scans the running application tree on a timer and if the process stops running it re-launches it... ? Not sure how to do that though.... An...

How to sort the following dictionary by the value of "remaining_pcs" or "discount_ratio"? promotion_items = { 'one': {'remaining_pcs': 100, 'discount_ratio': 10}, 'two': {'remaining_pcs': 200, 'discount_ratio': 20}, } EDIT What I mean is getting a sorted list of above dictionary, not to sort the dictionary itself. ...
Hi, I'd like to begin thinking about how I can scale up my algorithms that I write for data analysis so that they can be applied to arbitrarily large sets of data. I wonder what are the relevant concepts (threads, concurrency, immutable data structures, recursion) and tools (Hadoop/MapReduce, Terracota, and Eucalyptus) to make this happe...
