temp is a dictionary.  ## earlier code was temp = {}
i is a name from a list called names.
temp[i] is a reference into the dictionary using i as a key.
temp[i] = 0 binds that reference to 0.  Any previous value for temp[i]
is discarded.

temp is simply being used to track distinct names.  Any name from names
will have one and only one occurrence in the list of dictionary keys.

So temp.keys() will contain each name exactly once.  As covered in a
recent thread, the ordering of the names will probably be different from
the original names list.
