No, Python supports more collection types. You missed the tuple, the deq, the string and bytes for example. Actually the possibilities are infinite since you can make any object a collection by implementing some special methods and also you can subclass most built-in sequence times. solved Does Python include only 3 collection types?
Firstly, before you subclass an object, you should ask yourself “do I need to do this?”. Subclassing is a more complex way of interacting and extending the functionality of other classes, so you should make sure that what you are trying to achieve cannot easily be achieved through another, simpler method, such as delegation, notifications … Read more
They’re the same thing (in API Level 8+). Use match_parent. fill_parent (renamed MATCH_PARENT in API Level 8 and higher), which means that the view wants to be as big as its parent (minus padding) fill_parent: The view should be as big as its parent (minus padding). This constant is deprecated starting from API Level 8 … Read more
This is not so straightforward a problem because of having to consolidate the information by date. You also do not indicate what you want to happen should there be more than one identical code associated with a particular date. I chose to ignore it, and only list the unique codes, but you can modify the … Read more
I will approach your question like this: I assume you are firmly interested in big data database use already and have a real need for one, so instead of repeating textbooks upon textbooks of information about them, I will highlight some that meet your 5 requirements – mainly Cassandra and Hadoop. 1) The first requirement … Read more
You should let React render everything, and your job is only to tell React what to render and, in your case, how many times. For that, a counter can be used to track how many dynamically-added elements should be “injected” inside the <Example> component. A mindshift is needed here, since in your example you are … Read more
Ok, let’s work on this code a little. First let’s simplify building the paths. We have a network path and a local path. According to your current code the network path is built with a few variables comboBox1, comboBox2, and Environment.UserName, so let’s do it a little different: var networkPath = Path.Combine(@”\\network”, comboBox1.SelectedItem as string, … Read more
Look up iframes for a native HTML solution – https://developer.mozilla.org/en-US/docs/HTML/Element/iframe Alternatively, research using the jQuery .load() function – http://api.jquery.com/load/. However, the functionality of this is limited by the same origin policy solved Is it possible to use content of another website using jQuery? [closed]
In a generic method, you can only access the methods defined by the constraint on T (unless you use reflection or type checking/casting, both of which defeat the purpose of generics). If you constrain T to a Character (which I think you have to do to access Name and Health), then it should work (please … Read more
You can use binascii.hexlify(): In [25]: strs=b’\x0f\x00\x00\x00NR09G05164\x00′ In [26]: import binascii In [27]: binascii.hexlify(strs) Out[27]: b’0f0000004e52303947303531363400′ 3 solved Python : convert a hex string
just an example, you could pass your stack variable as an argument to the GetSum() function. private static int GetSum() { Stack<int> stack = new Stack<int>(); stack.Push(2); stack.Push(5); stack.Push(7); stack.Push(4); stack.Push(1); int sum = 0; foreach (int number in stack) { if (number % 2 != 0) { sum += number; } } return sum; … Read more
Use DateTime‘s createFromFormat $datetime = DateTime::createFromFormat(‘m/d/Y g:i a’, ’01/22/2013 2:33 pm’); echo $datetime->format(‘Y-m-d H:i:s’); solved Convert Normal Date to Timestamp [closed]
Put this around your code: while(true) { // CODE break; } and inside the else {} part: continue; Edit: You can also use LINQ, e. g. while(Controls.OfType<TextBox>().All(t => !t.Visible)) if you only have those boxes whose visibility changes inside the loop. 2 solved C# how do I this simple else to loop until true? [closed]
It works just fine: http://ideone.com/3E5Uec #include <iostream> using std::cout; using std::endl; class Cat { public: int name; Cat() : name(0) { } int getName() { return name; } }; int main() { Cat* pointer = new Cat(); pointer->name = 42; cout << “getName: ” << pointer->getName() << endl; cout << “name: ” << pointer->name << … Read more
Javascript and PHP don’t actually know anything about one another. However, you can use PHP to write to JavaScript. So in my_functions.php you could do this: <?php $myGlobalSongIndex = ‘0’; // or however you want to assign this else…. ?> <script type = “text/javascript”> var song_index = <?php print myGlobalSongIndex; ?>; Then in shortcodes.php on … Read more
