4,891,770 | 4,891,771 | Why we assigned the the value of variable "option" 1 before loops? | <p>I'm a new to programming and I chose python as my first language because its easy. But I'm confused here with this code:</p>
<pre><code>option = 1
while option != 0:
print "/n/n/n************MENU************" #Make a menu
print "1. Add numbers"
print "2. Find perimeter and area of a rectangle"
print "0. Forget it!"
print "*" * 28
option = input("Please make a selection: ") #Prompt user for a selection
if option == 1: #If option is 1, get input and calculate
firstnumber = input("Enter 1st number: ")
secondnumber = input("Enter 2nd number: ")
add = firstnumber + secondnumber
print firstnumber, "added to", secondnumber, "equals", add #show results
elif option == 2: #If option is 2, get input and calculate
length = input("Enter length: ")
width = input("Enter width: ")
perimeter = length * 2 + width * 2
area = length * width
print "The perimeter of your rectangle is", perimeter #show results
print "The area of your rectangle is", area
else: #if the input is anything else its not valid
print "That is not a valid option!"
</code></pre>
<p>Okay Okay I get every thing below the <code>Option</code> variable. I just want to know why we assigned the value of <code>Option=1</code>, why we added it on the top of the program ,and what is its function. Also can we change its value. Please make me understand it in simple language as I'm new to programming.</p>

<p>I did some googling around, but no solutions to this issue. It seems like list comprehensions mess with the current namespace, which seems really odd to me.</p>
<pre><code>print i
print [i for i in range(10)]
print i
</code></pre>
<p>The first is an error, the second prints range(10) as expected, and the last line prints 9, the 'last value of i' for the list comprehension. This is completely unexpected to me. What's more, if i was previously defined, it's now been overwritten.</p>

1,430,894 | 1,430,895 | What would be a good sample project to ask a prospective programmer to code during the hiring process? | <p>My understanding is that asking for a work sample is a good way to determine if someone has the skillset you are looking for, as some people just interview well. So I want to ask potential developers to write some sample code for me.</p>
<p>I'm looking for ideas on what kind of small project would be something they could do in an hour or two, and would show that they have a good grasp of OOP, good coding practices, etc. And what to look for once they finish - how to evaluate it fairly and usefully.</p>
<p>For context, I'm a small business owner, interviewing prospective developers, for PHP development on internal projects. I can code PHP but am not an expert (some of the work is refactoring code I've written to be better structured and consistent), and so I'm also looking for what to look for when evaluating the samples, given that I'm not a trained or super experienced programmer.</p>
<p>Especially for people who have done hiring of this type before and used this method.</p>
<p>I was also thinking I could give them some code to refactor, and see how they do on it. Has anyone ever given a refactoring test as part of the hiring process?</p>
<p>Clarification:
I'm not talking about coding during an interview. I'm talking about coding <em>instead</em> of an interview. For context the inspiration for this question came from this article in FastCompany about how work samples are better predictors of job success than interviews:</p>
<p>Why It May Be Wiser To Hire People Without Meeting Them

3,494,434 | 3,494,435 | can I use float[] to hold ints? | <p>we have one class which has one <code>float[]</code> and one <code>int[]</code>. Sometimes the user of that class needs put float valuse and sometimes int values, but will not be both for each instance.</p>
<p>We know all the possilbe float and int values will not be big (less than 100000). I am thinking we may not need the <code>int[]</code>, just use the <code>float[]</code> to hold int values when necessary. At the time we use them, we can cast them to int when necessary. One storage array will be much clear.</p>
<p>How do you think about my idea? put int into float[] will not lose anything. I am right?</p>
<p><strong>EDIT:</strong></p>
<p>One class have one <code>float[]</code> class variable and one <code>int[]</code> class variable to hold values for user. Users of that will use either float[] or int[] but not both. So we have get float[]and set float[] methods, AND get int[] and set int[] methods, and different constructors. I am thinking to simplify this class by remove int[] class variable and use a float[] for both int values and float values for different users.</p>

1,366,548 | 1,366,549 | How to Combine TemplateFields in ASP.Net GridView? | <p>Everyone.</p>
<p>I have a question when combining cells in GridView. I konw how to combine BoundField cells, but I do not know how to combine TemplateField cells in asp.net GridView.</p>
<p>EDIT:</p>
<p>Perhaps I did not make my question clearly and I am sorry about that. My question is that I use <code>GridView</code> to bind data from <code>db</code> and There is a field named <code>UserName</code>, one user has several records in the db, so I want to combine UserName in one cell(i can combine it correctly). In the same way, I want to do some operation to this user such as Add, Delete. So i put these operations into <code>TemplateField</code>, but i do not konw how to combine <code>TemplateField</code> like <code>BoundField</code>. I have a low reputation, so i can not post images</p>
<p>Any good ideas?</p>
<p>Sorry for my poor english! Thanks in advance.</p>

4,043,625 | 4,043,626 | How can I get the variable of outer function in Javascript | <p>If only string is allowed to pass into function process(), what should we do inside the function process() to access the array value. Eval is one of the method, but its usage is not suggested by many people.</p>
<pre><code>function demo2(name2)
{
var alpha = [];
alpha["a"] = "test1";
var bravo = [];
bravo["a"] = "test2";
function process(name)
{
alert(window[name]["a"]);
}
process(name2); // error
}
</code></pre>
<p>name2 can be "alpha" or "bravo" or many other arrays' name.</p>
<pre><code>var alpha = [];
alpha["a"] = "test1";
var bravo = [];
bravo["a"] = "test2";
function process(name)
{
alert(window[name]["a"]);
}
process("alpha");
</code></pre>
<p>For the second example, it works fine.
I just want to pass the string into the function and use it as the array name in the first example. I have the 2nd example and so I would like to know how I can do this inside a function. </p>
<p>What should I write inside the function process to alert the alpha and bravo variables?</p>

5,730,282 | 5,730,283 | numeric array sort() | <p>Is this part from the book "Learning PHP, MySql and Javascript by. Robin Nixon" wrong?</p>
<pre><code>numbers = [7, 23, 6, 74];
numbers.sort(function(a,b){return a - b});
</code></pre>
<p>output is 6,7,23,74</p>
<p>The book says:</p>
<blockquote>
<p>If the anonymous function inside sort() returns a value greater than zero, the sort assumes <strong>a</strong> comes before <strong>b</strong>.</p>
<p>If the anonymous function inside sort() return a value less than zero, the sort assumes <strong>b</strong> comes before <strong>a</strong>.</p>
<p>The sort runs this function across all the values in the array to determine their order.</p>
</blockquote>
<p>is this wrong? Because....</p>
<p><code>a</code> here is <code>7</code><br>
<code>b</code> here is <code>23</code></p>
<p><code>7 - 23 = -16</code> // a number less than zero. Book says it should b comes before a.</p>
<p>so the final output should be <code>74, 23, 7, 6</code></p>

<string name="foo">foo</string>
<string name="bar">@string/foo+bar</string>
<string name="else">@string/foo+else</string>
</resources>

<p>where the resource "bar" would yield the string "foobar". Its clear that '+' doesn't work here but is there some other option to achieve such a string concatenation, so that one could define a bunch of string resources that have a common prefix?</p>
<p>I realize of course that I could do such resource string concatenation at runtime but defining them statically in the resources would seem so much more elegant and simpler.</p>
