 Note that `for thing in stuff:` is not same as `for (thing in stuff):`.
 Here the `in` keyword is just a part of the for loop and it has a
 different meaning than it would have if we had `thing in stuff` without
-a `for`. Trying to do `for (thing in stuff):` creates an error:
-
-```py
->>> for (thing in stuff):

 Right now the while loop version might seem easier to understand for
 you, but later you'll realize that for loops are much easier to work
