<p style="color: grey"> Python recipe 580730 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/c/">c</a>, <a href="/recipes/tags/features/">features</a>, <a href="/recipes/tags/language/">language</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/switch/">switch</a>). </p> <p>This recipe shows a Python construct that can behave somewhat like C's switch statement. It is not a perfect one-to-one simulation. But it does have some of the features of the C switch. One feature not supported is the fall-through feature in C's switch.</p>

This implementation reconstructs Mooers' original algorithm in Python and supports only a limited number of TRAC primitives for demonstration purposes.</p>

It processes the character stream into appropriate class objects and stores these objects on a stack.</p>
