1,411,025 | 1,411,026 | Why does a python descriptor __get__ method accept the owner class as an arg? | <p>Why does the <code>__get__</code> method in a <a href="http://docs.python.org/reference/datamodel.html#implementing-descriptors">python descriptor</a> accept the owner class as it's third argument? Can you give an example of it's use?</p>
<p>The first argument (<code>self</code>) is self evident, the second (<code>instances</code>) makes sense in the context of the typically shown descriptor pattern (ex to follow), but I've never really seen the third (<code>owner</code>) used. Can someone explain what the use case is for it?</p>
<p>Just by way of reference and facilitating answers this is the typical use of descriptors I've seen:</p>
<pre><code>class Container(object):
class ExampleDescriptor(object):
def __get__(self, instance, owner):
return instance._name
def __set__(self, instance, value):
instance._name = value
managed_attr = ExampleDescriptor()
</code></pre>
<p>Given that <code>instance.__class__</code> is available all I can think of is that explicitly passing the class has something to do with directly accessing the descriptor from the class instead of an instances (ex <code>Container.managed_attr</code>). Even so I'm not clear on what one would do in <code>__get__</code> in this situation.</p>

<a href="http://stackoverflow.com/questions/2158395/flatten-an-irregular-list-of-lists-in-python">Flatten (an irregular) list of lists in Python</a> </p>
</blockquote>
<p>I've found solutions before, but I'm wondering what the fastest solution is to flatten lists which contain other lists of arbitrary length.</p>
<p>For example:</p>
<pre><code>[1, 2, [3, 4, [5],[]], [6]]
</code></pre>
<p>Would become:</p>
<pre><code>[1,2,3,4,5,6]
</code></pre>
<p>There can be infinitely many levels, so the solution would probably need to be implemented recursively.</p>
<p>Ideally, empty lists would be ignored like in the example above (no exceptions and errors). I expect this behaviour would emerge as a result of a neat recursive solution anyway.</p>
<p>Something else which doesn't affect me now, but I don't want to ignore is that some of the list objects can be strings, which mustn't be flattened into their sequential characters in the output list.</p>

2,398,343 | 2,398,344 | python: dict as prototype/template for another dict - std.lib way to solve this? | <p>I was looking for a way to create multiple ad-hoc copies of a dictionary to hold some "evolutionary states", with just slight generational deviations and found this little prototype-dict:</p>
<pre><code>class ptdict(dict):
def asprototype(self, arg=None, **kwargs):
clone = self.__class__(self.copy())
if isinstance(arg, (dict, ptdict)):
clone.update(arg)
clone.update(self.__class__(kwargs))
return clone
</code></pre>
<p>Basically i want smth. like:</p>
<pre><code>generation0 = dict(propertyA="X", propertyB="Y")
generations = [generation0]
while not endofevolution():
# prev. generation = template for next generation:
nextgen = generations[-1].mutate(propertyB="Z", propertyC="NEW")
generations.append(nextgen)
</code></pre>
<p>and so on.</p>
<p>I was wondering, if the author of this class and me were missing something, because i just can't imagine, that there's no standard-library approach for this. But neither the collections nor the itertools seemed to provide a similar simple approach.</p>
<p>Can something like this be accomplished with itertools.tee?</p>
<p><strong>Update</strong>:
It's not a question of copy & update, because, that's exactly what this ptdict is doing. But using update doesn't return a dict, which ptdict does, so i can for example chain results or do in-place tests, which would enhance readability quite a bit. (My provided example is maybe a bit to trivial, but i didn't want to confuse with big matrices.)</p>
<p>I apologise for not having been precise enough. Maybe the following example clarifies why i'm interested in getting a dictionary with a single copy/update-step:</p>
<pre><code>nextgen = nextgen.mutate(inject_mutagen("A")) if nextgen.mutate(inject_mutagen("A")).get("alive") else nextgen.mutate(inject_mutagen("C"))

I've figured out most of the other methods, such as insertion, post order and pre order, but I keep running into the same problem with the level order method</p>
<p>Here's the code:</p>
<pre><code>private DoubleStackQueue<Node> queue = new DoubleStackQueue<Node>();
//this is a queue that uses two stacks, one for the front and one for the back.
//it works just like a queue.
public String levelOrder(){
s = ""; //The s is a private String that is implemented earlier
queue.add(this);

Node node = (Node)queue.remove();

if (!(left.equals(null))) {queue.add(node.left);}
if (!(right.equals(null))) {queue.add(node.right);}
}
return s;

<p>The main problem that I am having is that, when the program gets to a leaf node, it still adds its children to the queue, even though there are no children, just null, so I'll get a queue that has two nulls in front of the actual item in it. I originally had the if statements as (left != null) and such, but that didn't work either. I'm just trying to figure out how to make the program recognize when there aren't any children.

For the client (GUI) side we tend to QT and C++. For the server side, we have been advised to use Java and indeed it looks like it is one of the languages being used most for server development.
Can anyone elaborate on the advantages offered by Java for server side development and why adopting it should make our life as developers easier and/or allow us to reach better results than if we used, let´s say, .NET or even C++?

1,173,905 | 1,173,906 | Python pixel manipulation library | <p>So I'm going through the beginning stages of producing a game in Python, and I'm looking for a library that is able to manipulate pixels and blit them relatively fast.</p>
<p>My first thought was pygame, as it deals in pure 2D surfaces, but it only allows pixel access through <code>pygame.get_at()</code>, <code>pygame.set_at()</code> and <code>pygame.get_buffer()</code>, all of which lock the surface each time they're called, making them slow to use. I can also use the <code>PixelArray</code> and <code>surfarray</code> classes, but they are locked for the duration of their lifetimes, and the only way to blit them to a surface is to either copy the pixels to a new surface, or use <code>surfarray.blit_array</code>, which requires creating a subsurface of the screen and blitting it to that, if the array is smaller than the screen (if it's bigger I can just use a slice of the array, which is no problem).</p>
<p>I don't have much experience with PyOpenGL or Pyglet, but I'm wondering if there is a faster library for doing pixel manipulation in, or if there is a faster method, in Pygame, for doing pixel manupilation. I did some work with SDL and OpenGL in C, and I do like the idea of adding vertex/fragment shaders to my program.</p>
<p>My program will chiefly be dealing in loading images and writing/reading to/from surfaces.</p>

<p>Then it gets 'stuck' at the line "engine.runAndWait()" and text to speech doesn't work. I am guessing that the problem lies with the rules of scoping with threads. right?
