3.21.1 PrettyPrinter Objects
</H2>

<P>
<tt class=class>PrettyPrinter</tt> instances have the following methods:

<P>
<dl><dt><b><a name="l2h-529"><tt class=method>pformat</tt></a></b> (<var>object</var>)
<dd>
Return the formatted representation of <var>object</var>.  This takes into
Account the options passed to the <tt class=class>PrettyPrinter</tt> constructor.
</dl>

<P>
<dl><dt><b><a name="l2h-530"><tt class=method>pprint</tt></a></b> (<var>object</var>)
<dd>
Print the formatted representation of <var>object</var> on the configured
stream, followed by a newline.
</dl>

<P>
The following methods provide the implementations for the
corresponding functions of the same names.  Using these methods on an
instance is slightly more efficient since new <tt class=class>PrettyPrinter</tt>
objects don't need to be created.

<P>
<dl><dt><b><a name="l2h-531"><tt class=method>isreadable</tt></a></b> (<var>object</var>)
<dd>
Determine if the formatted representation of the object is
``readable,'' or can be used to reconstruct the value using
<tt class=function>eval()</tt><a name="l2h-533"></a>.  Note that this returns false for
recursive objects.  If the <var>depth</var> parameter of the
<tt class=class>PrettyPrinter</tt> is set and the object is deeper than allowed,
this returns false.
</dl>

<P>
<dl><dt><b><a name="l2h-532"><tt class=method>isrecursive</tt></a></b> (<var>object</var>)
<dd>
Determine if the object requires a recursive representation.
