print the code which defined a lambda function
<p>I'd like to be able to print the definition code of a lambda function.</p>

<p>Example if I define this function through the lambda syntax:</p>

<pre><code>&gt;&gt;&gt;myfunction = lambda x: x==2
&gt;&gt;&gt;print_code(myfunction)
</code></pre>

<p>I'd like to get this output:</p>

<pre><code>x==2
</code></pre>
