Not with object literals (this has the same value during constructing of the literal that it did before-hand). But you can do var carousel = new (function() { this.$slider = $(‘#carousel1 .slider’); this.panes = this.$slider.children().length; })(); This uses an object created from an anonymous function constructor. Note that $slider and panes are public, so can … Read more
You can use such trick: myObject = new ArrayList<Object>(myTempObject); or use myObject = (ArrayList<Object>)myTempObject.clone(); You can get some information about clone() method here But you should remember, that all these ways will give you a copy of your List, not all of its elements. So if you change one of the elements in your copied … Read more
First thing that comes into my mind: read -r a b c <<<$(echo 1 2 3) ; echo “$a|$b|$c” output is, unsurprisingly 1|2|3
Why not just do this: var = None Python is dynamic, so you don’t need to declare things; they exist automatically in the first scope where they’re assigned. So, all you need is a regular old assignment statement as above. This is nice, because you’ll never end up with an uninitialized variable. But be careful … Read more
Your understanding is wrong. self is itself a parameter to that function definition, so there’s no way it can be in scope at that point. It’s only in scope within the function itself. The answer is simply to default the argument to None, and then check for that inside the method: def doSomething(self, a=None): if … Read more
Starting Python 3.8, and the introduction of assignment expressions (PEP 572) (:= operator), it’s now possible to capture the condition value (isBig(y)) as a variable (x) in order to re-use it within the body of the condition: if x := isBig(y): return x
You make the mistake of thinking of operator= as a two-argument function, where the side effects of the arguments must be completely evaluated before the function begins. If that were the case, then the expression i = ++i + 1 would have multiple sequence points, and ++i would be fully evaluated before the assignment began. … Read more
First off, var [a, b] = f() works just fine in JavaScript 1.7 – try it! Second, you can smooth out the usage syntax slightly using with(): var array = [1,2]; with (assign(array, { var1: null, var2: null })) { var1; // == 1 var2; // == 2 } Of course, this won’t allow you … Read more
Because string is assignable from char, and int is implicitly convertible to char.
All the expressions to the right of the assignment operator are evaluated before any of the assignments are made. From the Python tutorial: First steps towards programming: The first line contains a multiple assignment: the variables a and b simultaneously get the new values 0 and 1. On the last line this is used again, … Read more
