Too late. py> class Example: ... age = 0 ... py> Example.age 0 py> Example.aeg Traceback (most recent call last): File "<stdin>", line 1, in ? AttributeError: class Example has no attribute 'aeg' It works for instances too: py> Example().aeg Traceback (most recent call last): File "<stdin>", line 1, in ?
