nomenclature for Python function arguments
<pre><code>args = [4,5]
kwargs = {'x': 7}
func(a, b=2, *args, **kwargs)
</code></pre>

<p>What is the accepted nomenclature for referring to a, b, args, and kwargs?</p>

<p>In particular, fill in the blank here:</p>

<pre><code>'a' is a (_blank_) positional argument
'args' contains (_blank_) positional arguments
'b' is a (_blank_) keyword argument
'kwargs' contains (_blank_) keyword arguments
</code></pre>

<p>I'm looking for something like <strong>(<em>blank</em>) = {formal / arbitrary length / actual / variable position / fixed}</strong></p>

<p>Also please correct me if I'm wrong on the above.</p>
