class A:

     def __init__(self):
         self.x = 17
         self.setattr = self.custom_setattr

     def __setattr__(self, key, value):
         self.setattr(key, value)

     def setattr(self, key, value):
         object.__setattr__(self, key, value)

     def custom_setattr(self, key, value):
         print('custom_setattr:', key, '=', value)

a = A()
a.x = 1
print('a.x =', a.x)
