Is there a great tool to convert Python 3 to Python 2?<p>I&#x27;ve tried Pasteurize (part of python-future) but it just leaves the &quot;yield from&quot; statements in place, giving syntax errors. And 3to2 does even less, and seems to mostly be a framework for building tools like Pasteurize.<p>I know this isn&#x27;t easy, but JavaScript people do it with ES6 transpilers, and ES6 is more different from ES5 than Python 3 is from Python 2.
