<p>Basically, I have a script that does a simple calculation:</p>
<pre><code>divider = int(math.ceil(df.scale / 3000))
</code></pre>
<p>This is because I want ' divider' to return the value divided by 3000 and always rounded up. I want to use that value to help me return letters.</p>
<p>So, it goes like this:</p>
<p>if 1 returns then I want a to return 'A'
if 2 returns, then I want to create 'A', 'B'
if 3 returns, then I want to create 'A', 'B', 'C'
and so on....</p>
<p>My end result is, that I want to save some files. 'divider' will determine how many files I want to save and then each file will recursively be named with the letter in it (i.e. FileA, FileB, FileC...)</p>
<p>Ok, I know my question isn't exactly well put together, but I'm struggling with the logic, so if you need some clarity, please let me know.</p>

<p>For example some simple .hide(slow) is an example. As I understand, JQuery modifies HTML code of HTML components. A ".hide" without animation seems pretty "obvious", I guess "visibility:none" would do the trick.</p>
<p>But animation implies something more interesting I guess. The first idea is a loop that changes attributes and expect rendering is fast enough to make a smooth animation. But it sounds pretty "CPU abusive".</p>

1,495,343 | 1,495,344 | How to learn Python: Good Example Code? | <p>I have been dabbling in Python for a couple months now, read the online docs/tutorial and started playing with Django a bit as well... and I feel like I am starting to leave my formative toddler years and ready for some more serious code. Most everything I see is generally encapsulated in a single script or so large and unwieldy I don't know where to start. </p>
<p>I would really like to see an excellent example of some proper Python code, style, organization etc. and ideally a WHY associated with some of those decisions. Any ideas for where I should look next? I would prefer a simple console app with at most just a few extra .py files (maybe one package for good measure)...</p>
<p>Oh, and one more thing: The reason this is coming up is I have quite a bit of experience in Java and .NET where it is generally preferred to have one class definition per source file. That rarely seems to be the case in the python world (at least in my very limited exposure) and it just doesn't smell right to me. So maybe this is more Enterprise Python that hobbyist python or something.</p> | python | [7] |

16,178 | 16,179 | Printing derived class name in base class | <p>How can I print out the derived class name from the base class without chaining constructors all the way down. In other words is it possible to do this strictly from the base class without adding code in each derived class?</p>
<p>This is an example of what I got, and if there's a way I'd like to get rid of the constructor chaining.</p>
<p><strong>EDIT:</strong>
Ideally I am looking for something to add into the base class without having to edit all derived classes. At the moment my real code has got ~17 classes(with need for more), so something that could do the job straight from the base class would be ideal. Even if it's compiler specific (g++ or clang).</p>
<pre><code>#include <iostream>
class Base {
public:
Base(std::string id) {
std::cout<<"Creating "<<id<<std::endl;
}
};
class Child : Base {
public:
Child(std::string id) : Base(id) {}
Child() : Base(typeid(this).name()) {}
};
class GrandChild : Child {
public:
GrandChild(std::string id) : Child(id) {}
GrandChild() : Child(typeid(this).name()) {}
};
class GrandGrandChild : GrandChild {
public:
GrandGrandChild(std::string id) : GrandChild(id) {}

};
int main() {
GrandGrandChild *A = new GrandGrandChild();
GrandChild *B = new GrandChild();

<p>Ok, that sounds good. I can create a file. Except this method also throws a FileNotFoundException, so apparently something is amiss. Why would a function that is <em>supposed</em> to create a file if it's not found throw an exception if the file is not found???</p>

<ol>
<li><p>This pop-up script uses inline Javascript in a <code>href</code> link, to set the selected date into the <code>input</code> field, in the parent window, that is was called for. An example URL looks like:</p>
<pre><code><a href="javascript:window.opener.document.formname.field.value='03-10-2011';
window.close();">3</a>
</code></pre></li>
<li><p>The input field name, (e.g. <code>document.formname.field</code>), is passed to the script as a string parameter.</p></li>
</ol>
<p>I would like to add things done when that link is clicked (e.g. change background color of field, set flag, etc.). So while this DOES work, it's getting <strong>ugly</strong> fast.</p>
<pre><code><a href="javascript:window.opener.document.formname.field.value='03-10-2011';
window.opener.document.formname.field.style.backgroundColor='#FFB6C1';

How would I move these inline commands into a JS function? This would give me much cleaner URLs and code. The URL would now look something like </p>
