<p style="color: grey"> Python recipe 577864 by <a href="/recipes/users/4172762/">Jan Kaliszewski</a> (<a href="/recipes/tags/case/">case</a>, <a href="/recipes/tags/decorator/">decorator</a>, <a href="/recipes/tags/dispatcher/">dispatcher</a>, <a href="/recipes/tags/performance/">performance</a>, <a href="/recipes/tags/switch/">switch</a>). Revision 4. </p> <p>My approach to that common issue focuses on <strong>efficiency</strong> and <strong>elegant, declarative style</strong> of definition. That's why:</p> <ul> <li>The way switches work is based on unwrapped defaultdict/list lookup.</li> <li>The way you define switches is based on classes and easy-to-use decorators (note that you can use subclassing in a flexible way -- without any negative impact on efficiency!).</li> <li>Its use cases focus on a-lot-of-keys situations and it does not cover the <em>fall-through</em> feature (though you can reach its semantics if you really need that -- by calling class methods...).</li> </ul>

<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>

<p style="color: grey"> Python recipe 576715 by <a href="/recipes/users/4169206/">Jonas Haag</a> (<a href="/recipes/tags/case/">case</a>, <a href="/recipes/tags/case_insensitive/">case_insensitive</a>, <a href="/recipes/tags/replace/">replace</a>, <a href="/recipes/tags/str/">str</a>). Revision 2. </p> <p>REAL case insensitive version of <code>str.replace</code> that keeps the letter case of the original expression (Doesn't only replace <code>Foo</code> and <code>foo</code> to <code>...foo...</code> but to <code>...Foo..</code> and <code>...foo...</code>).</p>

Revision 9. </p> <p>When dealing with windows paths on a *nix system sometimes youll need to resolve case insensitive paths. While using a fat filesystem or making everything lowercase would work. this function means you can get python to take a case insensitive path and return the path with the correct case (if it exists).</p>
