Question
What will be the output of the following Python code?class A: def init(self): self._x = 5 class B(A): def display(self): print(self._x)def main(): obj = B() obj.display()main()Error, invalid syntax for object declarationNothing is printed5Error, private class member can’t be accessed in a subclass
Solution
The output of the given Python code will be 5.
Here's the step by step explanation:
-
Class A is defined with an instance variable _x which is set to 5 in the constructor.
-
Class B is defined which inherits from class A. It has a method display() which prints the value of _x.
-
In the main() function, an object of class B is created and the display() method is called.
-
Since class B inherits from class A, it has access to the _x variable. So, when the display() method is called, it prints the value of _x which is 5.
-
The main() function is then called to execute the program.
Therefore, the output of the program is 5.
