Python: Check instances and in subclasses a given class

Python Class ( Basic ): Exercise-8 with Solution

Write a Python program to create two empty classes, Student and Marks. Now create some instances and check whether they are instances of the said classes or not. Also, check whether the said classes are subclasses of the built-in object class or not.

Sample Solution:

Python Code:

class Student:
    pass 
class Marks:
    pass 
student1 = Student()
marks1 = Marks()
print(isinstance(student1, Student))
print(isinstance(marks1, Student))
print(isinstance(marks1, Marks)) 
print(isinstance(student1, Marks))
print("\nCheck whether the said classes are subclasses of the built-in object class or not.")
print(issubclass(Student, object))
print(issubclass(Marks, object)) 

Sample Output:

True
False
True
False

Check whether the said classes are subclasses of the built-in object class or not.
True
True
