Set Statements

The for statement works directly with `set`s, because they are iterable. A `set` is not a sequence, but it is like a sequence because we can iterate through the elements using a for statement.

Here we create three `set`s: `even`, `odd` and `zero` to reflect some standard outcomes in Roulette. The union of all three `set`s is the complete `set` of possible spins. We can iterate through this resulting `set`.

```>>> even= set( range(2,38,2) )
>>> odd= set( range(1,37,2) )
>>> zero= set( (0,'00') )
>>> for n in even|odd|zero:
print n

```
