In this example, we will learn how to access elements from 2-D NumPy arrays using the array indexing in Python.

### Source Code

```
import numpy as np
n = np.array([[1, 2, 3, 4], [5, 6, 7, 8]])
print('The first element of the first dimension:', n[0, 0])
print('The third element of the second dimension:', n[1, 2])
```

Output:

```
The first element of the first dimension: 1
The third element of the second dimension: 7
```
