You can assign them to a placeholder, with a method that always exists
but does nothing.
class NullObject(object):
def method(self, *args, **kw):
pas

This is a good practice anyway. Conditional existance of objects is
quite evil. Resorting to if defined('foo') is double-plus-ugly.
The other way, using try ... catch
try:
object.method()
catch NameEr
One way, define the object before it is used,
like this:
object = None
.
.
if object is not None:
object.method()
The other way, using try ... catch
try:
object.method()
catch NameError:
pass
for big programs, which is better, or any other way?
