<p style="color: grey"> Python recipe 580788 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/callbacks/">callbacks</a>, <a href="/recipes/tags/classes/">classes</a>, <a href="/recipes/tags/functions/">functions</a>, <a href="/recipes/tags/methods/">methods</a>, <a href="/recipes/tags/objects/">objects</a>, <a href="/recipes/tags/programming/">programming</a>, <a href="/recipes/tags/python/">python</a>). </p> <p>This is a follow-on to this recently posted recipe:</p> <p>Implementing function-based callbacks in Python: <a href="https://code.activestate.com/recipes/580787-implementing-function-based-callbacks-in-python/?in=user-4173351" rel="nofollow">https://code.activestate.com/recipes/580787-implementing-function-based-callbacks-in-python/?in=user-4173351</a></p> <p>This new recipe shows how to create and use callbacks in Python, using classes with methods, instead of plain functions, as was done in the recipe linked above. All other points such as reasons and benefits for using callbacks, are more or less the same as mentioned in the previous recipe, except that class instances can carry state around, so to that extent, the two approaches are different.</p> <p><a href="https://jugad2.blogspot.in/2017/04/python-callbacks-using-classes-and.html" rel="nofollow">https://jugad2.blogspot.in/2017/04/python-callbacks-using-classes-and.html</a></p>

<p style="color: grey"> Python recipe 580758 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/features/">features</a>, <a href="/recipes/tags/if/">if</a>, <a href="/recipes/tags/perl/">perl</a>, <a href="/recipes/tags/programming/">programming</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/trick/">trick</a>). </p> <p>This recipe shows how to simulate an unless statement (a sort of reverse if, like Perl has), in Python. It is just for fun and as an experiment, not meant for real use, because the effect of unless can easily be got by negating the sense of the condition in an if statement.</p> <p>More details and output here:</p> <p><a href="https://jugad2.blogspot.in/2017/02/perl-like-unless-reverse-if-feature-in.html" rel="nofollow">https://jugad2.blogspot.in/2017/02/perl-like-unless-reverse-if-feature-in.html</a></p>
