Given this example:
>>> x = [1, 2, 3]
>>> x = [1, 2]
Does the previous object that x is pointing to, the array of 1, 2, and 3, get destroyed by the garbage collector of Python? Or does it float around with nothing pointing at it?

3I believe it's garbage collected – LMc Nov 11 '16 at 15:37

Yes, it is garbage collected. However, exactly when the GC is triggered is unknown – inspectorG4dget Nov 11 '16 at 15:39

As far as I understand [this](http://stackoverflow.com/a/9449506/6614295), this is actually implementation dependent and not guaranteed to be collected at all. It will probably be gc'ed, though. – jotasi Nov 11 '16 at 15:39
