Numpy's `swapaxes(~)` method interchanges two axes.

WARNING

If you're looking to flip the columns and rows, use Numpy's transpose(~) method instead.

# Parameters

1. `a` | `array-like`

The input array.

2. `axis1` | `int`

The first axis.

3. `axis2` | `int`

The second axis.

# Return value

If `a` is a scalar, then a scalar is returned. Otherwise, a Numpy array is returned.

# Examples

Consider the following 2D array:

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

To swap the rows and columns:

``` np.swapaxes(a, 0, 1) array([[4, 6], [5, 7]]) ```

Notice how the rows and columns flipped.
