+
+What is the difference between arguments and parameters?
+--------------------------------------------------------
+
+:term:`Parameters <parameter>` are defined by the names that appear in a
+function definition, whereas :term:`arguments <argument>` are the values
+actually passed to a function when calling it.  Parameters define what types of
+arguments a function can accept.  For example, given the function definition::
+
+   def func(foo, bar=None, **kwargs):
+       pass
+
+*foo*, *bar* and *kwargs* are parameters of ``func``.  However, when calling
+``func``, for example::
+
+   func(42, bar=314, extra=somevar)
+
+the values ``42``, ``314``, and ``somevar`` are arguments.
+

 How do I write a function with output parameters (call by reference)?
