<pre><code>def psum(a,b,c):

how can I do <code>psum(*x,3)</code> --> an equivalent.</p>
<p>I do not want to do <code>x[0], x[1]</code> because a function returns <code>x</code> and calling it twice would be inefficient. Could one do <code>z = function(a)</code>. where <code>z = x</code>. and then do <code>z[0]</code>, <code>z[1]</code>.</p>
<p>But I'm wondering if one can do this otherwise and use positional arguments in such a way.</p>
<p>Also, <em>without</em> using a wrapper.</p>
<p>Edit: One cannot use names because I didn't implement the function and the function writers did not use named arguments :/</p>

<p>I don't know what "internal buffer" and "no-op" mean, but I think it says that <code>flush</code> writes data from some buffer to a file.</p>

file.write("foo")

<p>What should be done on the server side? what database or databases should fit better for each case?, what protocol is the best for this job...</p>

<blockquote>
<p>A method local class can only refer to the local variables which are marked <code>final</code></p>

<p>and in the explanation the reason specified is about the scope and lifetime of the local class object and the local variables on the heap, but I am unable to understand that. Am I missing anything here about <code>final</code>?? </p>

860,002 | 860,003 | Problem with comparing the results from a two-dimensional array! | <p>I'm developing a slot machine game. The player insert amount of money and makes a bet to play. And the goal of the game is to obtain as many rows, columns, and diagonals as possible of the same symbol. In the above example, obtained a profit when the upper and lower line have equal symbols, partly 2x lines. Depending on the number of rows with the same symbol the user gets paid as the profit system follows:</p>
<ul>
<li>A series provides 2 * bet</li>
<li>Two lines giving 3 * bet</li>
<li>Three rows giving 4 * bet</li>
<li>Four rows gives 5 * bet</li>
<li>Five lines gives 7 * bet</li>
<li>Fully playing field gives 10 * bet</li>
</ul>
<p>I dont know how to solve this problem with the paying? What code can I use? Should I use a for-loop? I'm new with c++ so I'm having trouble with this. I' been spending a lot of hours on this game and I just can't solve it. Please help me!
Here's a small part of my code for now: I just want to compare the results. </p>
<pre><code> srand(time(0));
char game[3][3] = {{'O','X','A'}, {'X','A','X'}, {'A','O','O'}};
for (int i = 0; i < 3; ++i)
{
int r = rand() % 3;
cout << " " <<game[r][0] << " | " << game[r][1] << " | " << game[r][2] << "\n";
cout << "___|___|___\n";
}
//......compare the result of the random symbols. ????

1,274,304 | 1,274,305 | Sorted collections: How do i get (extended) slices right? | <p>How can I resolve this?</p>
<pre><code>>>> class unslice:
... def __getitem__(self, item): print type(item), ":", item
...
>>> u = unslice()
>>> u[1,2] # using an extended slice
<type 'tuple'> : (1, 2)
>>> t = (1, 2)
>>> u[t] # or passing a plain tuple
<type 'tuple'> : (1, 2)
</code></pre>
<p>Rational: </p>
<p>I'm currently overengineering a sorted associative collection with the ability to return ranges of items. It is quite likely that I will want to store tuples of small integers (or even more pathologically wierd values like Ellipsis) in the collection (as keys), and will need some kind of sane way of differentiating extended slices from plain keys</p>
<p>In the one-dimensional case, it's sort of a non-issue. I can't think of any real reason I would want to collect values of type <code>slice</code>, especially since <code>xrange</code> values are functionally similar and more recognizable to pythonistas (in my judgement). All other extended slice constructs are tuples of <code>slice</code>, <code>Ellipsis</code> or plain-old python values</p>
<p>No other type of extended slice seems to be in common use for any kind of collection except multidimensional arrays as in NumPy.</p>
<p>I do need to support n-dimensional axes, similar to oct-trees or GiS indices. </p>
