NumPy's ndim property returns the number of dimensions (or axis) of the array as an int. Note that the notion of dimensions here is not mathematical (e.g. [1,2,3] is a one-dimension array, and not three-dimensional).

Examples

Getting the dimension of a 1D array


        
        
            
                
                
                    x = np.array([1,2,3]) 
x.ndim
                
            
            1

Getting the dimension of a 2D array


        
        
            
                
                
                    x = np.array([[1,2],[3,4]]) 
x.ndim
                
            
            2
