Python Implementations of Packing Algorithm

For an application I’m working on I need something like a packing algorithm implemented in Python see here for more details. The basic idea is that I have n objects of varying sizes that I need to fit into n bins, where the number of bins is limited and the size of both objects and bins is fixed. The objects / bins can be either 1d or 2d, interested in seeing both. (I think 3d objects is probably more than I need.)
