python class attribute

Question

i have a question about class attribute in python.

class base :
    def __init__ (self):
        pass
    derived_val = 1

t1 = base()
t2 = base ()

t2.deriv         


        

Answer 1

Check it out here and here.

The __class__ attribute is the class that the object belongs to. So in your example, the situation is similar to static variables. The t2.__class__.derived_val is referring to the variable that belongs to the class, not the variable that belongs to t2.
