I'm trying to create a 3-dimensional N*N*N list in Python, like such: n=3 l = [[[0,]*n]*n]*n Unfortunately, this does not seem to properly "clone" the list, as I thought it would: >>> l [[[0, 0, 0], [0, 0, 0], [0, 0, 0]], [[0, 0, 0], [0, 0, 0], [0, 0, 0]], [[0, 0, 0], [0, 0, 0], [0, 0, 0]]] >>> l[0][0][0]=1 >>> l [[[1, 0, 0], [1, 0, ...

When using custom classes with read-only properties that are of type List or similar (ie, ObservableCollection), it is still possible to 'get' the variable and call an Add() method on it to alter the content. Is there a way to stop this (without creating huge overloads of the List class) on 'external' access, or is it 'best practice' t...

I have a class of interest (call it X). I have a std::list<X*> (call it L). I have a function (call it F). F(L) returns a subset of L (a std::list<X*>) according to an algorithm that examines the internal state of each X in the list. I'm adding to my application a std::map<int,X*> (call it M), and I need to define F(M) to operate in ...

So my problem is that I've written a function that takes two Doubles, two Int, and a Calendar object on Android (Java). I believe the class provided to allow it to run in a separate thread, AsyncTask, accepts only one type of Object (but allows multiple) as an argument so I figured I might be able to put it in a List or a LinkedList or s...
