# NumPy arrays

Vectors and matrices are not available in core Python. In order to use them, you will have to import the NumPy library. Just as how you used dot notation to access methods of an object,
you can use the dot notation to access functions from a library. Recall that you can import a library using an alias. For example, to import `package`

as `pk`

, you can use:

```
import package as pk
```

Within the numpy library, you can use the `loadtxt()`

function to import files.
For example, you can load a file named `data.csv`

using numpy with `numpy.loadtxt('data.csv')`

. The `loadtxt()`

function has a `delimiter`

parameter which lets you specify that your data is separated by commas.
