python check if function accepts **kwargs
<p>is there a way to check if a function accepts **kwargs before calling it e.g.</p>

<pre><code>def FuncA(**kwargs):
    print 'ok'

def FuncB(id = None):
    print 'ok'

def FuncC():
    print 'ok'

args = {'id': '1'}

FuncA(**args)
FuncB(**args)
FuncC(**args)
</code></pre>

<p>When I run this FuncA and FuncB would be okay but FuncC errors with <code>got an unexpected keyword argument 'id'</code> as it doesn't accept any arguments</p>
