Question
What will be the output of the following Python code? class student: def init(self): self.marks = 97 self.__cgpa = 8.7 def display(self): print(self.marks)obj=student()print(obj._student__cgpa)
Solution
The output of the Python code will be 8.7.
Here's the step by step explanation:
-
A class named 'student' is defined with two attributes: 'marks' and '__cgpa'. The 'marks' attribute is public, while '__cgpa' is private due to the double underscore prefix.
-
The class also has a method named 'display' which prints the value of the 'marks' attribute.
-
An object 'obj' of the class 'student' is created.
-
The print statement is trying to access the private attribute '__cgpa' of the 'student' class. In Python, private attributes are not directly accessible. However, they can be accessed indirectly by using '_classname__attributename'.
-
So, 'obj._student__cgpa' is used to access the private attribute '__cgpa' of the 'student' class.
-
Therefore, the output of the code will be 8.7, which is the value of the '__cgpa' attribute.
