<p style="color: grey"> Python recipe 577947 by <a href="/recipes/users/4179946/">Andrea Crotti</a> (<a href="/recipes/tags/argparse/">argparse</a>, <a href="/recipes/tags/cli/">cli</a>). Revision 2. </p> <p>This little sample script looks up in locals() to determine all the callables in <em>main</em>.</p> <p>Then it passes them to parse_arguments, which show an help message as following usage:</p> <pre class="prettyprint"><code>prova.py [-h] {func2,func1} positional arguments: {func2,func1} optional arguments: -h, --help show this help message and exit </code></pre> <p>Useful to avoid duplication and make it easy to extend script functions.</p>
