recipe 577196

(<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>

<p>I was writing code to do bootstrapping on a set of data. I wanted a test case where if I asked for one bootstrap I would be returned the original data. lambdas and function references saved me from inefficient code.</p>
