How can I modify the local namespace of a function in python? I know that locals() returns the local namespace of the function when called inside it, but I want to do something like this (I have a reason why I want to do this where g is not accessible to f, but it's quicker to give a trivial, stupid example to illustrate the problem): def g(): pass def f(): g() f.add_to_locals({'g':g}) You've a couple of options. First, note that g in your example isn't actually a local to the function (ie. not assigned within it), it's a global (ie hasn't been assigned to a local variable). This means that it

Most C++ programmers like me have made the following mistake at some point: class C { /*...*/ }; int main() { C c(); // declares a function c taking no arguments returning a C, // not, as intended by most, an object c of type C initialized // using the default constructor. c.foo(); // compiler complains here. //... } Now while the error is pretty obvious once you know it I was wondering if there is any sensible use for this kind of local function declaration except that you can do it -- especially since there is no way to define such a local function in the same block; you have to define it

What is the advantage of local classes in Java or in any other language that makes use of this feature? They allow you to take logic out of the parent class and objectify it. This removes functionality from where it doesn't belong and puts it into its own class. But what if this new object is only needed for a short time, only for the duration of a single block of code? Well, that's where a local class fits in. coobird Here's an example of how an anonymous inner class, a local inner class, and a regular inner class might be present in a program. The example is looking at a myMethod method and

I'm trying to use multiple LOCAL strategies with PassportJS. I'm not trying to use local, facebook, and gmail, etc. I have two sets of users stored in separate objects and I want to use a local strategy to authenticate both. As it stands, I cannot use the same local strategy for both because they have different object properties which has me querying different objects. Is there any way to do this? OR any suggestions around this would be greatly appreciated. I don't think it's possible, because as far as I can see you need some method of 'handing off' a request to the second strategy when the
