title: Add a parameter into kwargs during function call?
body: <p>Is there a way to add key-value-pair into kwargs during the function call?</p>
  
  <pre><code>def f(**kwargs):
      print(kwargs)
  
  # ...
  
  pre_defined_kwargs = {'a': 1, 'b': 2}
  
  f(**pre_defined_kwargs, c=3)
  </code></pre>
  
  <p>Or even change the existing arguments?</p>
  
  <pre><code>f(**pre_defined_kwargs, b=3)  # replaces the earlier b=2
  </code></pre>
  
  <p>These two examples don't work, as they raise error</p>
  
  <pre><code>&gt;&gt;&gt; f(**pre_defined_kwargs, c=3)
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>Pointing at the comma in between the arguments</p>
