title: assign values to symbols in python debugger (pdb)
body: <p>Using <code>pdb.set_trace()</code>, I am trying to debug a series of expression in which <code>j</code> is used as an indexing variable. statements such as <code>j = 0</code> are not allowed since <code>j</code> is a reserved symbol for <code>pdb</code>. How can I get around this?</p>
