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

To check if a value is an instance of a specific class or any of its parent classes in Python using theisinstance() function and recursion, you can follow these steps: 1. Define a function to check if the value is an instance of the specific class or any of its parent classes:

1
2
3
4
5
6
7
8
9
10
11
12
13

   def is_instance_or_subclass(value, class_or_parent_classes):
  if isinstance(value, class_or_parent_classes):
 return True
  elif isinstance(class_or_parent_classes, tuple):
 for cls in class_or_parent_classes:
if issubclass(type(value), cls):
    return True
  else:
 if issubclass(type(value), class_or_parent_classes):
return True
  return False

2. Call theis_instance_or_subclass function and pass the value to be checked and the class or parent classes:

1
2
3
4
5
6
7
8
9

   value = SomeValue  # The value to be checked
   classes = (Class1, Class2, Class3, ...)  # The specific class or parent classes
   
   if is_instance_or_subclass(value, classes):
  print("The value is an instance of the specified class or its parent classes.")
   else:
  print("The value is not an instance of the specified class or its parent classes.")

In theis_instance_or_subclass function, theisinstance() function is used to check if the value is an instance of the specific class or any of its parent classes. If the value is found to be an instance of any of the classes, the function returnsTrue, indicating that the value is an instance of the specified class or its parent classes. If theclass_or_parent_classes argument is a tuple, the function performs additional recursion to check if the value is an instance of any of the classes in the tuple or their parent classes. If theclass_or_parent_classes argument is not a tuple, the function checks if the value is an instance of the single class or any of its parent classes. If the value is not found to be an instance of the specified class or any of its parent classes, the function returnsFalse. You can modify the code to include any additional checks or handle different types of class or parent class inputs. This approach allows you to dynamically check if a value is an instance of a specific class or any of its parent classes using recursion and theisinstance() function.
