<p>Find duplicate code in Python 2/3 source files. Write a nice report about it.</p>
<p>Works at the Abstract Syntax Tree level, which is a robust way to detect clones.
See this <a href="http://francois.boutines.free.fr/python-3.2-report.html">code duplicated in the Python 3.2 standard library</a>.</p>
<p><strong>Update</strong>: I cleaned the code a little bit, made it Python 2.7 compatible and faster.</p>

<p>If you need</p>
<ul>
<li>to define <strong>named tuple subclasses</strong> (including reusable abstract ones), adding/overriding some methods, in a convenient way;</li>
<li>to have the named tuple ABC (abstract base class) for <strong>isinstance/issubclass</strong> tests;</li>
<li>or simply would like to define your named tuple classes in a <strong>class-syntax-based and DRY way</strong> (without repeating type names...)</li>
</ul>
<p>-- <strong>this recipe is for you.</strong></p>
