Python Dictionaries • Python dictionaries are a powerful key / value data structure which allows the storing of different data types in the same data set • RenderMan's variable-length parameter list is represented in prman_for_python as a standard Python dictionary whose keys are the parameter declaration and whose values are scalars or sequences whose length is governed by the declaration and standard binding semantics Saturday, 23 October 2010
