If I had a list that ranged from 0 - 9 for example. How would I use the random.seed function to get a random selection from that range of numbers? Also how I define the length of the results.

```
import random

l = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
a = 10
random.seed(a)
length = 4

# somehow generate random l using the random.seed() and the length.
random_l = [2, 6, 1, 8]

```
