How do I check if a value is an instance of a specific class or any of its parent classes in Python using issubclass() function?

To check if a value is an instance of a specific class or any of its parent classes in Python using theissubclass() function, you can follow these steps: 1. Define the classes and their inheritance hierarchy: - Identify the specific class and its parent classes against which you want to perform the instance check. - Ensure that these classes are defined and accessible in your code. 2. Check for Instance of Specific Class or Parent Classes: - Use theissubclass() function to check if the value is an instance of the specified class or any of its parent classes. - Theissubclass() function takes two arguments: the value's class and the class (or tuple of classes) you want to compare against. - If the value's class is the same as the specified class or is a subclass of any of the specified classes,issubclass() will returnTrue. - Use a conditional expression to check the result ofissubclass() againstTrue. - Example:

1
2
3
4

def is_instance_of(value):
    classes = (ParentClass, SpecificClass)
    return issubclass(type(value), classes)

3. Use the function: - Call theis_instance_of() function and pass the value you want to check as an argument. - It will returnTrue if the value is an instance of the specified class or any of its parent classes, andFalse otherwise. - Example:

1
2
3
4
5
6
7

obj = SpecificClass()

if is_instance_of(obj):
    print("Value is an instance of SpecificClass or its parent classes")
else:
    print("Value is not an instance of the specified class or its parent classes")

By using theissubclass() function within a conditional expression, you can efficiently check if a value is an instance of a specific class or any of its parent classes. This approach allows for flexible type checking based on the provided class hierarchy, ensuring that the value's class matches or inherits from the specified classes.
