<p style="color: grey"> Python recipe 578136 by <a href="/recipes/users/4170919/">Ben Hoyt</a> (<a href="/recipes/tags/datetime/">datetime</a>, <a href="/recipes/tags/division/">division</a>, <a href="/recipes/tags/float/">float</a>). </p> <p>Python 2.x doesn't support dividing a timedelta by a float (only works with int). This function adds support for that.</p>

<p style="color: grey"> Python recipe 578132 by <a href="/recipes/users/2608421/">Stephen Chappell</a> (<a href="/recipes/tags/ctypes/">ctypes</a>, <a href="/recipes/tags/experiment/">experiment</a>, <a href="/recipes/tags/float/">float</a>, <a href="/recipes/tags/structure/">structure</a>). </p> <p>This is just an experiment to test my mental understanding of Python. It should not be used in any code as is violates the design principle that floats are to be immutable. The code also abuses <code>ctypes</code> and an understanding of how <code>floats</code> are currently arranged in memory. <code>set_float</code> is not guaranteed to work properly on any system, and may fail to work in the future if the data's arrangement changes.</p>

Revision 3. </p> <p>This module allows the user to create a more verbose set of ranges. Simple character ranges, and float ranges are supported.</p> <p>Supported Ranges:</p> <ul> <li>Basic Integer Ranges</li> <li>Float Ranges (as accurate as a float range can get)</li> <li>Simple character ranges (lowercase to lowercase, uppercase to uppercase, etc.)</li> </ul> <p>It should work in Python 2 and Python 3.</p> <p><strong>If you tested this for speed, or want to test this for speed, please post the results! (And your system specs)</strong></p> <p><strong>Edit:</strong> Found a really silly error of mine when using range instead of xrange in these functions!</p>

Revision 2. </p> <p>While using the built-in range function a while ago. I found an odd (perhaps bug) where the range function couldn't use float steps. I am not sure if that was intended for simplicity or not, but I wrote my own range function that goes beyond that anyway.</p>
