<p style="color: grey"> Python recipe 521907 by <a href="/recipes/users/57155/">Denis Barmenkov</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). </p> <p>Function becomes useful when we need hex value of crc32() result, even if it is negative.</p>

<p style="color: grey"> Python recipe 496929 by <a href="/recipes/users/2493385/">Egor Zindy</a> . </p> <p>I wrote this foldable panel to keep the look of my applications consistant with Windows. The code is extremely simple and is nowhere as flexible as the foldable panel already available in wxPython. Demo available in the code.</p>

<p style="color: grey"> Python recipe 496933 by <a href="/recipes/users/2493385/">Egor Zindy</a> (<a href="/recipes/tags/graphics/">graphics</a>). </p> <p>I use this utility to generate an "images.py" module which I use to provide images to my applications via wx.ImageFromStream . You can see an output in my other recipe "A foldable panel with a Windows XP look and feel". The utility is called "convert.py" and can be put in a folder together with the png images. When run, it'll generate the "images.py" file which can be moved to wherever it'll be used. The only thing I'm checking for is that "convert.py" won't overwrite an existing "images.py" file in the same directory.</p>

<p style="color: grey"> Python recipe 465219 by <a href="/recipes/users/2559120/">Maciej Obarski</a> (<a href="/recipes/tags/database/">database</a>). </p> <p>Python's struct library is too low-level for direct usage. This recipe (only 40 lines) shows how it can be turned into more developer-friendly tool.</p>
