17.1.5 AST Objects 
</H2>

<P>
Ordered and equality comparisons are supported between AST objects.
Pickling of AST objects (using the <tt class='module'><a href="module-pickle.html" tppabs="http://www.python.org/doc/current/lib/module-pickle.html">pickle</a></tt> module) is also
supported.

<P>
<dl><dt><b><a name='l2h-3024'><tt>ASTType</tt></a></b>
<dd>
The type of the objects returned by <tt class="function">expr()</tt>,
<tt class="function">suite()</tt> and <tt class="function">sequence2ast()</tt>.
</dl>

<P>
AST objects have the following methods:

<P>
<dl><dt><b><a name='l2h-3025'><tt class='method'>compile</tt></a></b> (<big>[</big><var>filename</var><big>]</big>)
<dd>
Same as <code>compileast(<var>ast</var>, <var>filename</var>)</code>.
</dl>

<P>
<dl><dt><b><a name='l2h-3026'><tt class='method'>isexpr</tt></a></b> ()
<dd>
Same as <code>isexpr(<var>ast</var>)</code>.
