# numpy.issubclass_

numpy.issubclass_(arg1, arg2)

  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.

  Parameters:
    arg1 class

      Input class. True is returned if arg1 is a subclass of arg2.

    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.

  Returns:
    out bool

      Whether arg1 is a subclass of arg2 or not.
