numpy.issubclass_() function

The issubclass_() function is used to determine if a class is a subclass of a second class.

issubclass_ is equivalent to the Python built-in issubclass, except that it returns False instead of raising a TypeError if one of the arguments is not a class.

Version: 1.15.0

Syntax:

numpy.issubclass_(arg1, arg2)

Parameter:

Name	Description	Required / Optional
arg1 : class	Input class. True is returned if arg1 is a subclass of arg2.	Required
arg2 : class or tuple of classes	Input class. If a tuple of classes, True is returned if arg1 is a subclass of any of the tuple elements.	Required

Return value:

out : bool - Whether arg1 is a subclass of arg2 or not.

Example: numpy.issubclass() function

>>> import numpy as np
>>> np.issubclass_(np.int32, int)
False
>>> np.issubclass_(np.int32, float)
False
