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

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

1
2
3
4
5
6
7
8
9
10
11

   def is_instance_of(value, target_class):
  # Check if the value is an instance of the target class
  if isinstance(value, target_class):
 # Additional validation rules
 # Add any additional validation rules as per your requirements
 if value.additional_validation():
return True
  
  # Check if the value's class has any parent classes
  if hasattr(value.__class__, '__bases__'):
 for parent_class in value.__class__.__bases__:
# Recursively check if the value is an instance of the parent class
if is_instance_of(value, parent_class):
    return True
  
  return False

2. Call theis_instance_of function and pass the value to be checked and the target class:

1
2
3
4

   value = SomeValue  # The value to be checked
   target_class = TargetClass  # The specific class or its parent classes to check against
   
   if is_instance_of(value, target_class):
  print("The value is an instance of the target class or any of its parent classes.")
   else:
  print("The value is not an instance of the target class or any of its parent classes.")

In theis_instance_of function, theisinstance() function is used to check if the value is an instance of the target class. If the value is an instance, the function proceeds with additional validation rules specific to your requirements. If the value's class has any parent classes (as indicated by the presence of__bases__ attribute), the function recursively checks if the value is an instance of each parent class. This allows you to check if the value is an instance of any of the parent classes in the inheritance hierarchy. The function returnsTrue if the value passes both theisinstance() check and any additional validation rules specific to your requirements or any of its parent classes. Otherwise, it returnsFalse. You can modify the code to include any additional checks or handle different types of 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 additional validation rules.
