That is it. You can also use the `sum`

command to combine a list of plot objects.

```
f=x^2+10
p=[]
for i in range(0,5):
p.append(plot(f-i,(x,-3,3)))
sum(p)
```

You can use list comprehensions in Python to shorten this significantly and produce the same result.

```
sum([plot(x^2+10 - i,(x,-3,3)) for i in range(0,5)])
```
