Python, suggestion for an return value design
<p>The question is vague because the problem is to abuse Python for a good cause.
Suppose i have python as program input:</p>

<pre><code>scf() # produces F,C that are somehow available globally
ci() # uses F,C 
</code></pre>

<p>question is, can <code>scf</code> modify the module of the caller?</p>

<p>and second case:</p>

<pre><code>F,C = scf() # F,C are not set globally.
</code></pre>

<p>So basically either capture value (x)or set it globally.
How can it be done?</p>
