Examples One-dimensional arrays Two-dimensional arrays Accessing values inside a tuple

Numpy's shape property returns the number of elements along each axis of the array as a tuple.

Examples

One-dimensional arrays


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

The , followed by nothing simply means that the array is a vector with 3 elements.

Two-dimensional arrays


        
        
            
                
                
                    x = np.array([[1,2,3],[4,5,6]]) 
print(x.shape)
                
            
            (2, 3)

This tells us that x has 2 rows and 3 columns.

Accessing values inside a tuple

Note that since the return type is just a tuple, you can access the actual numbers using [] syntax, like so:


        
        
            
                
                
                    x = np.array([1,2,3]) 
print(x.shape[0])
                
            
            3
