3.28 <tt class="module">repr</tt> --
         Alternate <tt class="function">repr()</tt> implementation</A>
</H1>

<P>

<A NAME="module-repr"></A>

<P>
The <tt class="module">repr</tt> module provides a means for producing object
representations with limits on the size of the resulting strings.
This is used in the Python debugger and may be useful in other
contexts as well.

<P>
This module provides a class, an instance, and a function:

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><span class="typelabel">class</span>&nbsp;<tt id='l2h-776' xml:id='l2h-776' class="class">Repr</tt></b>(</nobr></td>
  <td><var></var>)</td></tr></table></dt>
<dd>
  Class which provides formatting services useful in implementing
  functions similar to the built-in <tt class="function">repr()</tt>; size limits for
  different object types are added to avoid the generation of
  representations which are excessively long.
</dl>

<P>
<dl><dt><b><tt id='l2h-777' xml:id='l2h-777'>aRepr</tt></b></dt>
<dd>
  This is an instance of <tt class="class">Repr</tt> which is used to provide the
  <tt class="function">repr()</tt> function described below.  Changing the attributes
  of this object will affect the size limits used by <tt class="function">repr()</tt>
  and the Python debugger.
</dd></dl>

<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
  <td><nobr><b><tt id='l2h-778' xml:id='l2h-778' class="function">repr</tt></b>(</nobr></td>
  <td><var>obj</var>)</td></tr></table></dt>
<dd>
  This is the <tt class="method">repr()</tt> method of <code>aRepr</code>.  It returns a
  string similar to that returned by the built-in function of the same
  name, but with limits on most sizes.
</dl>
