3.28.2 Subclassing Repr Objects
The use of dynamic dispatching by
<tt class=
"method">Repr.repr1()
</tt> allows
subclasses of
<tt class=
"class">Repr
</tt> to add support for additional built-in
object types or to modify the handling of types already supported.
This example shows how special support for file objects could be
<div class=
"verbatim"><pre>
def repr_file(self, obj, level):
if obj.name in ['
<stdin
>', '
<stdout
>', '
<stderr
>']:
print aRepr.repr(sys.stdin) # prints '
<stdin
>'
