Python specify lambda arguments as a function argument
<p>Is there any possibility to specify how many arguments a lambda as a function argument can take?</p>

<p>For example:</p>

<pre><code>def func(k=lambda x:return x**2):
   return k
</code></pre>

<p>Could i specify, if k is not the standard lambda, that k is supposed to take exactly one argument?</p>

<p>Max</p>
