Remember this example with For loops?
<iframe src="https://trinket.io/embed/blocks/504306d90d" width="100%" height="500" frameborder="0" marginwidth="0" marginheight="0" allowfullscreen></iframe>
Let's see it in interactive code:
```python.run
import turtle
tina = turtle.Turtle()
import random
tina.shape("turtle")
tina.speed(500)
tina.penup()
for location in [150, 75, 0, -75, -150]:
tina.color('#%06x' % random.randint(0, 2**24 - 1))
tina.goto(location,0)
tina.begin_fill()
tina.circle(10)
tina.end_fill()
tina.goto(-70,-50)
tina.color('#000000')
tina.goto(0,-80)
```
The `list` that the Turtle uses for the heights at which she should draw circles is `[150, 75, 0, -75, -150]`. Try changing those to different numbers.
