The isinstance() function in Python is used to check whether an object is an instance of a particular class or not. The function takes two arguments: the first argument is the object to be checked, and the second argument is the class (or tuple of classes) that the object is being checked against.

        The general syntax of the isinstance() function is as follows:

isinstance(object, classinfo)

        Here, object is the object that is being checked, and classinfo is the class (or tuple of classes) that the object is being checked against.

        For example, the following code uses the isinstance() function to check whether an object is an instance of a particular class:

class MyClass:
    pass

my_object = MyClass()

if isinstance(my_object, MyClass):
    print("my_object is an instance of MyClass")
else:
    print("my_object is not an instance of MyClass")

        In this example, the isinstance() function is used to check whether the object my_object is an instance of the MyClass class. If the object is an instance of the class, the code prints the message "my_object is an instance of MyClass", otherwise it prints the message "my_object is not an instance of MyClass".

        The isinstance() function is useful for checking the type of an object at runtime, which can be helpful when you need to perform different actions based on the type of the object.
