38,484,823 | Are there any large Python libraries that avoid OOP? | <p>I'm a developer working at a company that primarily uses Python. I have a <em>strong</em> dislike of OOP; I feel it is almost always the wrong tool for the job and quickly makes code unmanageable. In our code base, I would like to avoid using objects / classes / inheritance, etc as much as possible.</p>
<p>I know how to write good functional code in "functional" languages like SML (I use the scare quotes because it is difficult to define what a functional language is). I would ideally like to do the same in Python. Python doesn't force OOP; it has modules, and first-class functions, etc, but it seems like all the Python code I see makes heavy use of classes, and often inheritance as well (even multiple inheritance!). This is both true of the code I work with as well as third-party libraries I've seen.</p>
<p>Are there good examples of large Python libraries that are written in a more functional style that I could learn from? Or has anyone had success in their own private code with this? I don't just want to start writing all my code in a functional style only to run into some pitfalls later down the line.</p>

38,516,230 | Helpp! New to programming (loops are my nightmare) ! Working with arrays? Bubble sorting? | I'm doing this assignment where by using the Bubble Sort Algorithm, create a program that asks a user for a number of integers.
The program will then ask the user to input as many integers as the user requested and fill the values of the arrays into it.
Afterwards, the program user output the following:
a. Show Number List from File (Unsorted)
b. Show Sorted List
c. Show Greatest number
d. Show Smallest Number
e. Show the Median Value
f. Show the Average Value
So far I have this :
import java.util.Scanner;

String strUser;
int intSize;
int[] intNum;
//Input
Scanner scn=new Scanner(System.in);
//Process/Output
System.out.println("Please enter the number of values you would like to enter:");
strUser=scn.nextLine();
intSize=Integer.parseInt(strUser);
intNum=new int [intSize];
for(int i=0; i < intNum.length; i++)
{
System.out.println("Please enter for index value of "+i+":");
intNum[i]=scn.nextInt();
}
}
}
which outputs this (for example):
Please enter the number of values you would like to enter: 3
Please enter for index value of 0:
47
Please enter for index value of 1:
89
Please enter for index value of 2:
42
BUILD SUCCESSFUL (total time: 13 seconds)
Now how do I get all these inputed numbers into an array so I can be them in a list, and then use the bubble sorting to order them, and so on..
Like this:
Unsorted order:
47,89,42
Sorted order:
42, 47, 89

38,528,466 | Why is this c program NOT causing a segmentation fault with alphanumeric values? | In its simplest form the program is
int main(){
int x;
scanf("%d",x);
}
when we give this program any numeric value as input it fails by producing a segfault signal which is what we should expect.
But if we instead give it any alphanumeric value it DOES NOT fails !!!
what is going on in the scanf that produces this behavior ?
This is the backtrace from gdb when running it with a numeric value
(gdb) bt
#0 0x00000034e7456ed0 in _IO_vfscanf_internal () from /lib64/libc.so.6

38,536,488 | Link does not work without http:// protocols (php) | I use php and I have an input that the user types in a link to his website and the link should appear for others to view it or open it. I'm testing the input and the problem is the link does not work unless I types either http:// or https:// before the mentioned URL and I think some one might just write www.foo.com without writing the hhtp:// .
The link automatically substitutes the http:// or https://with the root of my website ( or at least that's what I guess ), because I'm working with XAMP and the URL appears as so : localhost/MyFooProjectFile/www.foo.com .
How to make links work without the protocols or substitute the none mentioned protocol with the right one before my user's link ?
Note : I know the question might seem stupid (cause who is the idiot who thinks a link could work without protocol), but what makes me wonder is I write in the address bar of my browser www.foo.co and it would take me there, without me menthionioning the protocols.
PLease note that I do not have the code in the time of writing the question. Do not downvote just comment if code is crucial, Thanks. | <php> | 2016-07-22 23:15:23 | LQ_EDIT |

38,553,348 | I am a newbie in programming specifically C#.. Need help in solving some programming puzzles | I am trying to get the output like this: 4 then 5 then 6 then 7 then 8 then 9 then 10 then 11 then 12 then 13.
The biggest challenge I'm facing is to make sure the word "then" doesn't appear after the last number(13).
Below is my code
class Program
{
static void Main(string[] args)
{
int start;
for(start = 4; start<=13; start++)
Console.Write(start +" then " );
Console.ReadKey();
}
}

38,554,814 | How to resolve 'A get or set accessor expected' compile error C# | Hi I'm trying to write some code that will set a countdown timer in C# but I'm getting a compile error A get or set accessor expected
Looking around it seems that I'm missing some () somewhere, but I'm not really sure where the issue is.
Here's the code that I'm having trouble with, any help or advice would be appreciated.
public static class TimeController { static DateTime TimeStarted; static DateTime TotalTime;
public static void StartCountDown(TimeSpan totalTime)
{
TimeStarted = DateTime.UtcNow;
TotalTime = totalTime;
}
public static TimeLeft
get
{
var result = DateTime.UtcNow - TimeStarted; //THIS IS THE LINE THAT HAS THR ERROR
if (result.TotalSeconds <= 0)
return TimeSpan.Zero;
return result;
}

38,555,435 | Dispaly a grid in html | I am a social sciences researchers and I am trying to create a task for an online study. The task is the following: a grid with shaded and white squares will be displayed and the task consist in counting the nb of shaded squares (as in the example). Different grids, with varying number of shaded squares will be shown to the participants in the study.
I have the program that randomly generates an array of 0s and 1s in javascript and stores the number of 1s (answer for the problem=nb of coloured squares).
What I need is to be able to display the array of numbers in a grid in html. Any ideas would be very welcome and extremely helpful.
