I guess your question is about the dangling else ambiguity contained in many grammars; in bash there isn’t such a thing. Every if has to be delimited by a companion fi marking the end of the if block. Given this fact (besides other syntactic errors) you’ll notice your example isn’t a valid bash script. Trying … Read more
you can either use alternative to GOOGLEFINANCE (depends on what exactly are you up to) or if you want to stick with it you can wrap it into IFERROR: =IFERROR(GOOGLEFINANCE(your_formula_here), GOOGLEFINANCE(same_formula_here)) or even: =IFERROR(IFERROR( GOOGLEFINANCE(your_formula_here), GOOGLEFINANCE(same_formula_here)), GOOGLEFINANCE(same_formula_here))
Sometimes you have to ask the question before you can find the answer. Dan Ray had a similar problem and solved it with a very different solution. – (UIView*)hitTest:(CGPoint)point withEvent:(UIEvent *)event { UIView* result = [super hitTest:point withEvent:event]; if ([result.superview isKindOfClass:[UIPickerView class]]) { self.scrollEnabled = NO; } else { self.scrollEnabled = YES; } return result; … Read more
You are either confusing static with abstract as kihero says, or you are muddling the concept with a class that has static methods (which is just a class that happens to have static methods). A static nested class is just a nested class that doesn’t require an instance of its enclosing class. If you are … Read more
{inner_k: myfunc(inner_v)} isn’t a dictionary comprehension. It’s just a dictionary. You’re probably looking for something like this instead: data = {outer_k: {inner_k: myfunc(inner_v) for inner_k, inner_v in outer_v.items()} for outer_k, outer_v in outer_dict.items()} For the sake of readability, don’t nest dictionary comprehensions and list comprehensions too much.
This groups each 3 elements in the order they appear: new_list = [data_list[i:i+3] for i in range(0, len(data_list), 3)] Give us a better example if it is not what you want.
The core of your question is why Inner.Inner is a different type than Inner. Once you understand that, your observations about compile time and generated IL code size follow easily. The first thing to note is that when you have this declaration public class X<T> { public class Y { } } There are infinitely … Read more
While initialization the anonymous struct is only known under its type name (in your case A). The members and functions associated with the struct are only exported to the outside after the instance exists. You have to supply a valid instance of A to initialize MemberA: b := B { A: A{MemberA: “test1”}, MemberB: “test2”, … Read more
I believe that in Java, you can simply nest enums, as long as your non-enum constants come first. enum Action { FOO, BAR; enum MOVE { UP, DOWN, LEFT, RIGHT } } This compiles for me and gives me the behavior you were looking for.
Here are the functions, which reconstructs the dictionaries just use this loadmat instead of scipy.io’s loadmat: import scipy.io as spio def loadmat(filename): ”’ this function should be called instead of direct spio.loadmat as it cures the problem of not properly recovering python dictionaries from mat files. It calls the function check keys to cure all … Read more
