how to program functions with alternative return value signatures in python? (next() for alternative iterators)
<p>e.g. so that these would both work - is it possible?</p>

<pre><code>(val,VAL2) = func(args) 
val = func(args)
</code></pre>

<p>Where <strong>val</strong> is <strong>not a tuple</strong></p>

<p>For example I'd like these to work for my custom object <strong>something</strong></p>

<pre><code>for item in something:
    do_item(item) #where again item - is not a tuple

for (item,key) in something:
    do_more(key,item)
</code></pre>

<p>I thought that I need to implement next() function in two different ways... </p>

<p><strong>edit:</strong> as follows from the answers below, this should not really be done.</p>
