Numpy's isscalar(~) method checks whether if the provided parameter is a scalar.

Note that numbers, strings, np.inf and np.NaN are all scalars in Numpy.

Parameters

1. num | any

The input object.

Return value

A single boolean is returned, where True means num is a scalar.

Examples

Basic usage

a = np.array([2])
np.isscalar(a)
False
np.isscalar(5)
True
np.isscalar(np.inf)
True
np.isscalar(np.NaN)
True
