Hi as you will see I am not very familiar with python and numpy but whant to learn it to myself.
The following code is a very basic sudoku solver which works fine for simple examples. Altough it runs I still have the feeling its not very pythonic.

I'd like to merge two dictionaries (d1 and d2) into a new dictionary (d_match). I'd like that the d_match dictionary contains only the items corresponding to the “shared” keys (aka: the keys found in both d1 and d2).
I'm trying the following code, but the result is that d_match contains all keys ...

I have a console class which describes rectangle of cells which a user can index by passing in a coordinate:
width, height = 80, 25
console = Console.new(width, height)
x, y = 2, 5
point_on_screen = Point.new(x, y)
console[point_on_screen] = 'a'
I am now wond...
Given an iterator, of type iterator, return the elements of all the contained iterators.

First of all, I am sorry if I have to move this question here, considering that in stackoverflow it still dons't have any answer yet since yesterday.

I am learning PySide, trying to implement Widgets within a main window. My goal right now is very simple: I want to place a QLabel, with independently defined event handling, inside a main window that has its own event handling:

I am solving ROCK problem on SPOJ. I have used bottom up dynamic programming approach for this problem. Time complexity for this is O(n^3). I am using following code:
#include<stdio.h>
#include<string.h>
#include<math.h>
#define MAX 210
#define NEG_INFINITY -1000
int sellable(int a[MAX], int i,...

I took a little bit from all the answers to my previous question Threshing: Sieve of Eratosthenes.
This may be bordering on Code Golfing, but I think that I have a pretty good piece of code here.
Is there any major concepts that I am overlooking, it still seems super simple?

I'm brand new to programming (in general) and C++ (in particular). I'm learning the basics of classes and objects.
I'm trying to do the following:
a) create a class called X. It has 4 member functions, with 0 arguments, 1 argument, 2 arguments and 3 arguments, respectively.
b) in main(), m...
