NumPy's `view(~)` method creates a new view of the array with the same data.

# Parameters

1. `dtype` | `data type` | `optional`

The data-type descriptor of the returned view.

2. `type` | `type` | `optional`

The type of the returned view. Defaults to type preservation.

# Examples

## Changing the value of the view

Suppose we have the following:

``` x = np.array([4,5,6])x array([4, 5, 6]) ```

We create a view:

``` y = x.view()y array([4, 5, 6]) ```

We mutate the view y:

``` y[0] = 2y array([2, 5, 6]) ```

This results in the original array x being mutated as well:

``` x array([2, 5, 6]) ```

## Changing the shape of the view

Suppose we have the following:

``` x = np.array([4,5,6,7])x array([4, 5, 6, 7]) ```

We create a view:

``` y = x.view()y array([4, 5, 6, 7]) ```

We then change the shape of our view y:

``` y.shape = (2,2)y array([[4, 5],       [6, 7]]) ```

We then see that our original array x does not reflect this change:

``` x array([4, 5, 6, 7]) ```
