<p style="color: grey"> Python recipe 580718 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/ascii/">ascii</a>, <a href="/recipes/tags/error/">error</a>, <a href="/recipes/tags/exception/">exception</a>, <a href="/recipes/tags/handler/">handler</a>, <a href="/recipes/tags/shutdown/">shutdown</a>, <a href="/recipes/tags/terminate/">terminate</a>, <a href="/recipes/tags/utilities/">utilities</a>, <a href="/recipes/tags/utility/">utility</a>). </p> <p>This recipe shows how to trap the KeyboardInterrupt and EOFError Python exceptions so that they do not crash your program. As a vehicle to show this, it uses a small Python utility that shows the ASCII code for any ASCII character you type.</p>

<p style="color: grey"> Python recipe 577258 by <a href="/recipes/users/4173505/">Trent Mick</a> (<a href="/recipes/tags/error/">error</a>, <a href="/recipes/tags/logging/">logging</a>, <a href="/recipes/tags/main/">main</a>, <a href="/recipes/tags/mainline/">mainline</a>, <a href="/recipes/tags/script/">script</a>). Revision 5. </p> <p>This is a recipe is often use for the mainline of my Python scripts. With this recipe your Python script will:</p> <ul> <li>gracefully handle <code>Ctrl+C</code> (i.e. <code>KeyboardInterrupt</code>)</li> <li>log an error (using the <code>logging</code> module) for uncaught exceptions, importantly <strong>with the file and line number</strong> in your Python code where the exception was raised</li> <li>gracefully ignore a closed output pipe (common when the user pipes your script through <code>less</code> and terminates that)</li> <li>if your script logger is enabled for <code>DEBUG</code> level logging, a full traceback will be shown for an uncaught exception</li> </ul> <p>Presumptions:</p> <ul> <li><p>you have a global <code>log</code> variable a la:</p> <pre class="prettyprint"><code>import logging log = logging.setLevel("scriptname") </code></pre></li> <li><p>your script's entry point is a function <code>def main(argv): ...</code></p></li> </ul>
