vice.yields.ccsne.settings.keys
===============================

Returns the keys of the CCSN yield settings dataframe.

**Signature**: vice.yields.ccsne.settings.keys()

.. note:: By nature, this function will simply return a list of all
	elements that are built into VICE - the same thing as
	``vice.elements.recognized``.

Example Code
------------
>>> import vice
>>> elements = vice.yields.ccsne.settings.keys()
>>> tuple(elements) == vice.elements.recognized
	True
