Each visit method can call the <tt class="method">emit()</tt> method to emit a new bytecode. The basic code generator is specialized for modules, classes, and functions. An assembler converts that emitted instructions to the low-level bytecode format. It handles things like generator of constant lists of code objects and calculation of jump offsets. <P> <DIV CLASS="navigation"> <p><hr> <table align="center" width="100%" cellpadding="0" cellspacing="2"> <tr> <td><A href="module-compiler.visitor.html"><img src="../icons/previous.gif" border="0" height="32" alt="Previous Page" width="32"></A></td> <td><A href="compiler.html"><img src="../icons/up.gif" border="0" height="32" alt="Up One Level" width="32"></A></td> <td><A href="sgi.html"><img src="../icons/next.gif" border="0" height="32" alt="Next Page" width="32"></A></td> <td align="center" width="100%">Python Library Reference</td> <td><A href="contents.html"><img src="../icons/contents.gif" border="0" height="32" alt="Contents" width="32"></A></td> <td><a href="modindex.html" title="Module Index"><img src="../icons/modules.gif" border="0" height="32" alt="Module Index" width="32"></a></td> <td><A href="genindex.html"><img src="../icons/index.gif" border="0" height="32" alt="Index" width="32"></A></td> </tr></table> <b class="navlabel">Previous:</b> <a class="sectref" href="module-compiler.visitor.html">19.4 Using Visitors to</A> <b class="navlabel">Up:</b> <a class="sectref" href="compiler.html">19.
