<p style="color: grey"> Python recipe 577929 by <a href="/recipes/users/4179768/">Alexander James Wallar</a> (<a href="/recipes/tags/element/">element</a>, <a href="/recipes/tags/elements/">elements</a>, <a href="/recipes/tags/find/">find</a>, <a href="/recipes/tags/finder/">finder</a>, <a href="/recipes/tags/list/">list</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/search/">search</a>). </p> <p>This module/function lets you find a 2 dimensional list of indices for elements you are looking for in a super list. Example:</p> <p>find([1,1,1,2,1,2,3,3],[1,2,3])</p> <p>returns: [[0, 1, 2, 4], [3, 5], [6, 7]]</p>

<p style="color: grey"> Python recipe 577858 by <a href="/recipes/users/4178886/">Lucio Santi</a> (<a href="/recipes/tags/case/">case</a>, <a href="/recipes/tags/class/">class</a>, <a href="/recipes/tags/design/">design</a>, <a href="/recipes/tags/finder/">finder</a>, <a href="/recipes/tags/match/">match</a>, <a href="/recipes/tags/oop/">oop</a>, <a href="/recipes/tags/pattern/">pattern</a>, <a href="/recipes/tags/suitable/">suitable</a>, <a href="/recipes/tags/switch/">switch</a>). </p> <p>This recipe implements a design pattern useful for performing an object-oriented case analysis for a particular object (or a collection of objects as well). Essentially, it is an alternative to complex if-then-else or switches. Modelling each case with a particular class, the Concrete Class Finder searches for an appropriate case/class that applies to the given object/s. Once found, this class can be used in an homogeneous way, independently of the object/s previously considered.</p>
