<p>So the question is in first case why python just not consider value of variable to <code>n = 8</code> by ignoring the zero on left side instead of raising an exception. As in second case it is still considering all zeros to a valid value.</p>
<p>Consider another case.</p>
<pre><code>>>> n = '0008'

880,027 | 880,028 | substitute of function pointers in python | <p>I have worked in low level C programming for years and I don't have enough exposure to Object oriented approaches. In C if I was developing some layered architecture then each layer has interfaces defined by function pointers. The advantage of that the whole layer can be replaced by just setting those function pointers at initialization to another layer. </p>
<p>I want the same thing but this time in Python. What is the coolest way to achieve that. To give a little background to my problem, I have a data generator which can output records to different mediums. The medium is specified at the configuration time. I don't want to use if or switch statements here. The best way was to use function pointers in C but what are the options available here in Python. Any Object oriented approaches are also appreciated.</p>
<p>Thanks</p>

1,947,094 | 1,947,095 | calling a function from another function by 'onclick' event | <p>What I am trying to do is, call a function from another function by clicking a radio button in that function. Here is the code I have worked on so far-</p>
<pre><code><script type="text/javascript">

button2.style.visibility="visible";
}
function onlyapp()
{
button2.style.visibility="visible";
button1.style.visibility="hidden";
}
</script>
</code></pre>
<p>Now, whenever rad1 is clicked, i want mainalso() to run, as might be clear from the code. Since I am fairly new to JavaScript, I don't know where i'm making the mistake, in syntax or conceptually. Also, the first function (before mainalso()) is add(), and in it I repeatedly append same content on clicking a button in my body. I hope it is clear what I want to do. When rad1 is clicked, i want both buttons (button1 and button2) to appear, but on clicking rad2 I want only one button to appear. Both have been set to 'hidden' visibility at first.
Please help me out. Sorry if it seems unclear, I tried my best..
Thank you.</p>

Can anyone confirm this?</p>
<p>Here's what I've tried. I setup a button on a view, link it to a method on my viewcontroller, and make sure it works fine. My view has a UIWebView control on it as well. If I run the project on the simulator or on the iPhone, there are no issues. Then I add this code to the button's method.</p>
<pre><code>[theWebView stringByEvaluatingJavaScriptFromString:@"alert('Hi there!');"];
</code></pre>
<p>When I run the project, I can click the button and see the 'Hi there' prompt and I can click OK to dismiss it. Usually 4-5 seconds later the simulator crashes. I occasionally see the <code>"__TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION__"</code> error, but not consistently; sometimes there's no error. It also doesn't always crash the first time. Sometimes I go to another page, and then try it again, and it crashes.</p>
<p>If I put the same code in the webPageDidFinishLoad event it works fine. But I'd like the code to be called when the user demands it so that event doesn't suit my needs.</p>

2,360,254 | 2,360,255 | Question Concerning a CodingBat Beginner Problem | <p>So I've been practicing my Java programming skills on the CodingBat website, when I came across <a href="http://codingbat.com/prob/p146974" rel="nofollow" title="this">this</a> problem. In it, you have to make a simple method that takes in an array of integers of dynamic length, check to see if the elements in the array are in increasing order (1, 2, 3, 15678, etc), and return "true" if true, or "false" if there is an integer out of order.</p>
<p>Firstly, I initialize a boolean variable named "result". Then, I iterate through the array of integers passed by the method. If the current index value is less than the next index value, I set "result" to "true", and repeat the loop. Else, I'll set "result" to "false", break out of the loop and set "result" to "false". After the FOR loop, I return "result".</p>
<p>However, I've been receiving an error message that "result" has not been initialized properly. I can kinda understand the confusing with the JVM, however I thought that setting the value for "result" inside of the IF/ELSE statements would solve that.</p>
<p>Here is a copy of the code that I have done so far:</p>
<p>EDIT: For posterity, I have edited out the wrong code for the correct code that works. Feel free to check it out and learn from it as I have. It appears that I forgot (among other things) to check the actual ELEMENT inside of the FOR loop, not necessarily the reference itself. Thanks a ton, everyone!</p>
<pre><code>public boolean scoresIncreasing(int[] scores) {
for (int i = 0; i < scores.length - 1; i++) {
if (scores[i] > scores[i + 1]) {
return false;
}
}
return true;
