Jan 2, 2023'Variable' is a class variable to begin with. But then, obejct_1.Variable is created and assigned a value of 1. Obejct_2.Variable, which is also an instance variable, has had no value assigned to it.

Oct 3, 2023Answer is A. The instruction object_1.Variable += 1 creates a new attribute to object_1 and it does not modify class variable 'Variable': object_1.__dict__ ==> {'value':0, 'variable':1} Since class variable 'Variable' is still 0, object2.variable will be 0, then: object_2.Variable (0) + object_1.value (1) = 0 + 1 = 1
