There are two simple ways to find the index of the largest value in a Numpy array.

The first way is to use the `argmax(~)`

function of the Numpy array:

```
x = np.array([3,5,2,1])x.argmax()
1
```

Here, 1 is returned because the largest value (i.e. 5) is located at index 1.

The second way is to use the `argmax(~)`

static function of the Numpy module:

```
x = np.array([3,5,2,1])np.argmax(x)
1
```
