<p style="color: grey"> Python recipe 521884 by <a href="/recipes/users/1499228/">Chris Arndt</a> (<a href="/recipes/tags/multimedia/">multimedia</a>, <a href="/recipes/tags/pygame/">pygame</a>, <a href="/recipes/tags/sound/">sound</a>, <a href="/recipes/tags/sysadmin/">sysadmin</a>). Revision 4. </p> <p>This simple script shows how to play back a sound file using the mixer module from the pygame library. If you have pygame installed, this will work on all major platforms. The mixer module supports WAV and OGG files with many different sample rates, bits per sample and channels. The script will play back all supported files given on the command line sequentially.</p>

<p style="color: grey"> Python recipe 473846 by <a href="/recipes/users/1499228/">Chris Arndt</a> (<a href="/recipes/tags/sysadmin/">sysadmin</a>). </p> <p>This modules provides a few handy functions to retrieve the path names of some windows system directories from the registry [1] and the environment. These path names can be different depending on OS version, installation language, current user and personal setup. Because of this, they should not be included statically in your program.</p>

<p style="color: grey"> Python recipe 435883 by <a href="/recipes/users/1499228/">Chris Arndt</a> (<a href="/recipes/tags/threads/">threads</a>). Revision 3. </p> <p>A thread pool is a class that maintains a pool of worker threads to perform time consuming operations in parallel. It assigns jobs to the threads by putting them in a work request queue, where they are picked up by the next available thread. This then performs the requested operation in the background and puts the results in a another queue.</p> <p>The thread pool class can then collect the results from all threads from this queue as soon as they become available or after all threads have finished their work. It's also possible, to define callbacks to handle each result as it comes in.</p> <p>Basic usage:</p> <pre class="prettyprint"><code>&gt;&gt;&gt; main = TreadPool(poolsize) &gt;&gt;&gt; requests = makeRequests(some_callable, list_of_args, callback) &gt;&gt;&gt; [main.putRequests(req) for req in requests] &gt;&gt;&gt; main.wait() </code></pre> <p>See the below for a longer, annotated usage example.</p>

<p style="color: grey"> Python recipe 134571 by <a href="/recipes/users/1499228/">Chris Arndt</a> (<a href="/recipes/tags/text/">text</a>). </p> <p>This Module contains a function that formats paragraphs of text to have a certain linewidth, optionally stretching lines to that width by filling word gaps with spaces. In other words, it does left-justified/word-wrapped and block formatted paragraphs.</p>
