Ordered and equality comparisons are supported between AST objects.
Pickling of AST objects (using the
<tt class=
"module"><a href=
"module-pickle.html">pickle
</a></tt> module) is also
<dl><dt><b><tt id='l2h-
4950' xml:id='l2h-

</tt></b></dt>
The type of the objects returned by
<tt class=
"function">expr()
</tt>,
<tt class=
"function">suite()
</tt> and
<tt class=
"function">sequence2ast()

AST objects have the following methods:
