numpy.issubclass_() function - Python

numpy.issubclass_() function - Python

The numpy.issubclass_() function tests if one class is a subclass of another. It's similar to the built-in Python function issubclass(), but with some differences to handle NumPy specific types and issues.

Syntax:

numpy.issubclass_(arg1, arg2)

Parameters:

  • arg1: Class to be checked
  • arg2: Class, type, or tuple of classes and types

Returns:

True if arg1 is a subclass of arg2. Returns False otherwise.

Example:

Here's a simple example of how to use numpy.issubclass_():

import numpy as np # Create two custom classes for demonstration class ParentClass: pass class ChildClass(ParentClass): pass # Check using numpy.issubclass_() print(np.issubclass_(ChildClass, ParentClass)) # True print(np.issubclass_(ParentClass, ChildClass)) # False print(np.issubclass_(int, (int, float))) # True print(np.issubclass_(float, (int, float))) # True print(np.issubclass_(str, (int, float))) # False

In this example, ChildClass is a subclass of ParentClass, so np.issubclass_(ChildClass, ParentClass) returns True.

As you can see, the numpy.issubclass_() function is quite straightforward and provides a method to check the subclass relationships, especially in contexts where you're working extensively with NumPy and its associated types.
