Numpy's full(~) method creates a new Numpy array whose entries are filled by the specified value.

Parameters

1. shape | int or sequence<int>

The dimensions of the resulting array.

2. fill_value | scalar

The value to fill the entires.

3. dtype | string or type | optional

The desired data type for the resulting array. By default, the type is inferred from the fill_value.

Return value

A Numpy array whose entries are filled by the specified value.

Examples

One-dimensional arrays

To create a 1D Numpy array of size 5, with the value 2 as the entries:


        
        
            
                
                
                    np.full(5, 2)
                
            
            array([2, 2, 2, 2, 2])

Here, the data-type is inferred as int64:


        
        
            
                
                
                    np.full(5, 2).dtype
                
            
            dtype('int64')

Two-dimensional arrays

To create a 2D Numpy array with 2 rows and 3 columns, with the value 5 as the entries:


        
        
            
                
                
                    np.full((2,3), 5)
                
            
            array([[5, 5, 5],
       [5, 5, 5]])
