<p style="color: grey"> Python recipe 577196 by <a href="/recipes/users/4172918/">Daniel Cohn</a> (<a href="/recipes/tags/generator/">generator</a>, <a href="/recipes/tags/iterable/">iterable</a>, <a href="/recipes/tags/iterator/">iterator</a>, <a href="/recipes/tags/loop/">loop</a>, <a href="/recipes/tags/peeking/">peeking</a>, <a href="/recipes/tags/window/">window</a>). </p> <p>Oftentimes a programmer needs to peek into an iterator without advancing it, a task for which many good solutions already exist. But what if the intrepid coder needs a fast and pythonic way to 'window' the data? This recipe demonstrates how to wrap any iterable with a class that adds two methods, prev and peek.</p>

It will NOT work on any other platform!</p> <p>(It MIGHT work on AMIGA OS3.5x and 3.9x with Python 2.4.6, but totally untested and I hold no responsibility for the outcome when trying it.)</p> <p>It is a DEMO to peek a byte inside _ANY_ memory address inside the standard CPU 68EC020 16MB boundary.</p> <p>I experimented with this several years ago and have decided to finally release it. I do await the flak!</p> <p>It works from Python Versions 1.4.0 to 2.0.1 for the classic AMIGA.</p> <p>Ensure that the T: Volume exists on the running machine.</p> <p>See inside the code and text below it also as to how it works...</p> <p>Bazza, G0LCU...</p>
