Details

EDIT You can retrieve some information sp = SharedParameterElement CPython3 doc.ParameterBindings.get_Item(sp.GetDefinition()) IronPython doc.ParameterBindings.Item[sp.GetDefinition()]

EDIT 2 Workaround

# CPython3
params = FilteredElementCollector(doc).OfClass(ParameterElement).ToElements()

def get_binding(param):
    binding = doc.ParameterBindings.get_Item(param.GetDefinition())
    if binding:
        return param.GetDefinition().Name, binding

OUT = filter(None, [get_binding(p) for p in params])
