What will be the output of the following code? class A: def __init__(self,v = 1): self.v = v def set(self,v): self.v = v return v a = A() print(a.set(a.v + 1))

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

• 1
• 0
• 2
• 3

Explanation: Let’s analyze the code:

• The A class constructor creates an instance variable named v equal to the default value passed to the constructor’s parameter v, which is 1.
• The set method creates its own v variable, and returns the value passed to it.
• The a object is created, and the set method is called, which returns the v value equal to 1 + 1.
• The result 2 is printed to the console.
