Which of the following is correct?

    def __init__(self):
        self.count = 5
        self.count = count + 1

print(a.count)
  • 560

Solution

The correct answer is "Error".

Here's why:

In the __init__ method of class A, self.count=count+1 is incorrect. The variable count is not defined in this scope. If you want to increment the self.count by 1, you should write self.count=self.count+1.

So, when you try to create an object of class A using a=A(), Python will throw an error because it doesn't know what count is in the expression count+1.

Here's the corrected code:

class A: 
    def __init__(self): 
        self.count=5 
        self.count=self.count+1

a=A()
print(a.count)

This will output 6 because self.count is initially set to 5 and then incremented by 1.
