...
I don't know of a standard function in Python, but this works for me:
Python 2

Python ValueError: too many values to unpack [duplicate]
...acked into the tuple "k, m", hence the ValueError exception is raised.
In Python 2.x, to iterate over the keys and the values (the tuple "k, m"), we use self.materials.iteritems().
