<p style="color: grey"> Python recipe 574459 by <a href="/recipes/users/2071240/">Shekhar Tiwatne</a> (<a href="/recipes/tags/extending/">extending</a>). Revision 5. </p> <p>Many times I find myself write a cli that takes two/more positional arguments. Something like mycp file1 file2 [options] I have to write extra code everytime to show correct usage/hints to user if he invokes command this way mycp file1 Positional arguments are required ones unlike optional arguments.</p> <p>The solution below lets cli writer add a positional argument so parser can generate usage friendlier to positional args.</p> <p>Some inspiration: <a href="http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/573441" rel="nofollow">http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/573441</a></p>

Revision 2. </p> <p>Sometimes you define properties in base class and override the getter setter methods in derived classes. Then you find out the base class though has derived properties are still pointing to baseclasse's methods not the overriden ones.</p>
