Nowhere in particular, it's a consequence of putting things together. 
The part that Antoon isn't mentioning is that he's presuming the 
function f(x) returns a list or something similar that we can then 
index.  You're more likely to see that sort of code written as:

a = f(x)
a[n] = x *n

which makes it look a lot less magical.
