What will be the effect of running the following code? class A: def __init__(self,v): self.__a = v + 1 a = A(0) print(a.__a)

class A:
    def __init__(self,v):
        self.__a = v + 1
 
 
a = A(0)
print(a.__a)

• 2
• The code will raise an AttributeError exception
• 0
• 1

Explanation: The following code will result in the AttributeError exception, because the A object does not have the attribute __a. The __a variable is a private instance variable, and an attempt to access or modify it from outside the class will result in an AttributeError.

Modifying the private attribute __a and changing it to public (a) will result in the following output: 1.
