<p style="color: grey"> Python recipe 578158 by <a href="/recipes/users/4171013/">Charlie Clark</a> (<a href="/recipes/tags/case/">case</a>, <a href="/recipes/tags/comparison/">comparison</a>, <a href="/recipes/tags/switch/">switch</a>, <a href="/recipes/tags/ternary/">ternary</a>). </p> <p>Although Python now has something similar to ternary operator with the result if ... else other result construction and this allows chaining (adding additional conditions on the if side, this soon becomes unreadable. A common use case is to filter values by ranges so I wrote the following when porting some code from PHP once I found I no longer understand the logic for a simple three-way filter.</p>

<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>

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>
