ERROR in Cannot use 'in' operator to search for 'providers' in null 出现这个问题的原因是，在使用懒加载的时候，没有指定module，没有找到相关的提供信息。 const routes: Routes = [ {path:'login',component:loginComponent}, { path: 'about', loadChildren: './home/home/home.module'},] ...
Lambda I used this Lambda function: "=LAMBDA(range,IFERROR(TOCOL(FILTER('3 times'!K3:CL3,(range=3))),""))(K4:CL4)" and it worked perfectly. I then inserted it into name manger, created a name and it fails to work. It seems to input the wrong cell references?
x<-Integer(5)x%isa%Integer Type declarations Type constraints can be added to a function. These constraints specify the type of each input argument in addition to the return type. Using this approach ensures that the arguments can only have compatible types when the function is called. The fi...
and instead use unpacking: Python >>> pairs = [(1, 'a'), (2, 'b'), (3, 'c')] >>> sum(x for x, _ in pairs) 6 The use of underscore (_) is a Pythonconventionindicating that you can ignore the second value of the pair. sum() takesa unique argument, so the ...

In an ideal world (short of Excel resolving the array-of-arrays issue natively), I would have a black box into which I would feed the relevant array, the attack approach (by row, by column), the function to apply (TEXTSPLIT(), in this example) and the argument(s...
An argument I often hear for monolithic functions, is that it reduces the no. of functions, which makes them easier to manage. On the surface, this seems to make sense. But the more I think about it the more it strikes me that the no. of function would only be an...
