Question

Is it possible to define a python class which not return an AttributeError exception if an attribute is called but not existing in the class instance? Like

class A():
    pass

a = A()
a.tutu <==not raising AttributeError

thanks

You could define a __getattr__ method on your class. See the documentation.

Here’s a simple example that gives all missing attributes the value “Default”:

>>> class Foo(object):
...     def __getattr__(self, attr):
...         return "Default"
>>> f = Foo()
>>> f.someJunk
'Default'
