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
