4,913,067 | 4,913,068 | How does Python interpret this conditional? | <p>The problem I am working on is explained below:</p>
<blockquote>
<blockquote>
<p>2.1) Write a program that asks a user to input a color.
If the color is black or white, output "The color was black or white".
If it starts with a letter that comes after "k" in the alphabet,
output "The color starts with a letter that comes after "k" in the
alphabet". (Optional: consider both capitalized and non-capitalized
words. Note: the order of the alphabet in Unix and Python
is: symbols, numbers, upper case letters, lower case letters.)</p>
</blockquote>

<p>Here is the authors solution:</p>
<pre><code>#!/usr/bin/env python
#
# guess a color
#
answer = raw_input ("Please enter a color: ")
if (answer == "black") or (answer == "white"):
print "The color was black or white."
elif answer >= "k":
print "The color starts with a letter that comes after \"k\" in the alphabet."
</code></pre>
<p>This is my answer to the problem:</p>
<pre><code>#!usr/bin/env python
#
#This program asks the user to input a color
color = raw_input("Please, enter a color, any color.")

print "The color starts with a letter that comes after 'k' in the alphabet."
else:
print "The color was niether black nor white."
</code></pre>
<p>I am having trouble understanding how the authors solution works, specifically for identifying if, "The color starts with a letter that comes after "k" in the alphabet".</p>

3,587,550 | 3,587,551 | DLL exporting only certain templatized functions | <p>Hey all, so this seems to be a rather strange issue to me. I have a very simple templatized container class which is part of a DLL. The entire class is defined in a header file, to allow automatic template generation. Now another part of the DLL actually requests a certain template type to be generated, so the code should exist within the DLL. However, when using the object from another executable, the constructor/destructor, plus multiple other functions work, however 2 functions are not found by the linker. Following are is the code for these two functions, as well as for a working function.</p>
<pre><code>const T** getData() const
{
return m_data;
}
int getNumRows() const
{
return m_nRows;
}
int getNumCols() const
{
return m_nCols;
}
</code></pre>
<p>So the getNumRows() and getNumCols() functions are not found by the linker, however the getData() function is. Is this a common problem, do the functions need to have a templatized parameter in order to be generated?</p>
<p>@1 800 INFORMATION</p>
<p>I have exported this from the DLL via a standard macro:</p>
<pre><code>#ifdef ACORE_EXPORTS
#define ACORE_API __declspec(dllexport)

#define ACORE_API __declspec(dllimport)

71,880 | 71,881 | When do I need inflaters? | <p>I'm reading the book 'Hello, Android'. In the Sudoku example, it uses a options menu. It needs a MenuInflater that we use to read the menu definition from XML and turns it into a real view.
To use button, textview, or many other views, I don't need to inflate them.</p>
<p>My question is, in what situations, I need inflaters? Why doesn't Android treat menus like other views?</p>

5,195,209 | 5,195,210 | what is document.getElementById? | <p><strong>consider the following code:</strong></p>
<pre><code><script>
function testFunc(){

$(function(){
var g = document.getElementById , w = window.testFunc ;
//g
alert(typeof(g));
alert(String(g));

//w
alert(typeof(w));
alert(String(w));
alert(w instanceof Object);
alert(w instanceof Function);
//run it
alert(g('t'));

});
</script>
</code></pre>
<h2><strong>the code behaves the same in modern browser(chrome,IE 9,Firefox).And the result is:</strong></h2>
<p>typeof => "function"<br/>
String => "function #funcName#{[native code]}"<br/>
instanceof Object => true<br/>
instanceof Function => true<br/>
it is a little weird, we can easily invoke <code>w</code> by using <code>()</code>, but for <code>g</code>, we must invoke it like this:</p>
<pre><code>g.call(document,elementId);
</code></pre>
<p>When it comes to IE 6, the result is totally diffrent:</p>
<hr>
<p>//g<br/>
<b>typeof => "object"</b><br/>
String => "function getElementById{[native code]}"<br/>
instanceof Object => false<br/>
instanceof Function => false<br/>
//w<br/>
<b>typeof => "function"</b><br/>
String => "function testFunc{alert('test')}"<br/>
instanceof Object => true<br/>
instanceof Function => true<br/>
what is more,we must run g and w directly by using '()', and we can not invoke g like this:</p>
<pre><code>g.call(document,'t')
</code></pre>
<p>this will cause an error.
So here is my question: what is <code>document.getElementById</code>, function or object, and what is the diffrence between <code>g</code> and <code>w</code>?</p>

532,782 | 532,783 | firing an Event by code in android | <p>Wondering if there is any way to build and fire an event (e.g. on click event) in android applications programmatically. </p>
<p>Thanks.</p>
<p>sorry, it seems question is not clear enough, let me explain a bit more:</p>
<ul>
<li>I have an Activity (lets call it A) with multiple views (5 ImageView for example).</li>
<li>And a normal Java class (lets call it B) which is used by my Activity.</li>
<li>There is an instance of B in my Activity. </li>
<li>If user click on a View (Image View) the view OnClickListener calls a method in B </li>
<li>In B, if operation is successful, it will call back a method in activity again. </li>
<li>in activity method, It will change image or state for clicked ImageView.</li>
</ul>
<p>in the other hand:</p>
<p>click on view (x) in Activity -------> B.doSomething() --------> A.bIsDone() -----> change image for view (x) </p>
<p>with normal execution, its working and there is no problem.</p>
<p>the problem is that I want to simulate this process to be automatic, my code looks like this:</p>
<pre><code> while (!b.isFinished()) {
try {
b.doSomething(<for View x>);
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
</code></pre>
<p>The issue is that, it won't render anything, until the end of the loop. </p>
<p>I tried to put the loop in another Thread, but its throwing exception:</p>
<pre><code> android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.
</code></pre>
<p>what can i do for this issue? i was think generate an click event on view (by code), to see it can help or not.</p>
<p>what is your solution?
Thanks </p>

3,836,694 | 3,836,695 | Matching strings for multiple data set in Python | <p>I am working on python and I need to match the strings of several data files. First I used pickle to unpack my files and then I place them into a list. I only want to match strings that have the same conditions. This conditions are indicated at the end of the string. </p>
<p>My working script looks approximately like this:</p>
<pre><code>import pickle
f = open("data_a.dat")
list_a = pickle.load( f )
f.close()
f = open("data_b.dat")
list_b = pickle.load( f )
f.close()
f = open("data_c.dat")
list_c = pickle.load( f )
f.close()
f = open("data_d.dat")
list_d = pickle.load( f )
f.close()
for a in list_a:
for b in list_b:
for c in list_c
for d in list_d:
if a.GetName()[12:] in b.GetName():
if a.GetName[12:] in c.GetName():
if a.GetName[12:] in d.GetName():
"do whatever"
</code></pre>
<p>This seems to work fine for these 2 lists. The problems begin when I try to add more 8 or 9 more data files for which I also need to match the same conditions. The script simple won't process and it gets stuck. I appreciate your help.</p>
<p>Edit: Each of the lists contains histograms named after the parameters that were used to create them. The name of the histograms contains these parameters and their values at the end of the string. In the example I did it for 2 data sets, now I would like to do it for 9 data sets without using multiple loops. </p>
<p>Edit 2. I just expanded the code to reflect more accurately what I want to do. Now if I try to do that for 9 lists, it does not only look horrible, but it also doesn't work.</p>

4,380,122 | 4,380,123 | Getting an array with the content of attributes | <p>I have a class in my code in C# where I want to get all the attributes from a nested class in an array with the size of the number of parameters and the content of all of them in an array of objects. Like these:</p>
<pre><code>class MyClass {

public const string E = "E";
