<div dir="ltr">I realized after I fired off my response that this was still bugging me... it appears that the documentation is incorrect<br><br>from 2.1 Built-in Functions (v2.5 in case it matters... a quick search of bugs doesn't seem to show anything though)<br>

</dt><dd>Return a <font style="background-color: rgb(49, 106, 197);" color="#ffffff">reverse</font> iterator. <var>seq</var> must be an object which
supports the sequence protocol (the __len__() method and the <tt class="method">__getitem__()</tt> method with integer arguments starting at
<code>0</code>). <span class="versionnote">New in version 2.4.</span> </dd></dl>the above appears to only be true for lists. For tuples and strings it creates a reverse OBJECT which behaves slightly differently (notably by not including a len() method as you noticed)<br>
<br>I can't find how to actually create a "tuplereverseiterator" or "stringreverseiterator" objects... nor does there appear to be a way to create a "reversed" object from a list... <br><br>
