It is simple to write a function that returns a list of the numbers of the
Fibonacci series, instead of printing it::
- >>> def fib2(n): # return Fibonacci series up to n
+ >>> def fib2(n): # return Fibonacci series up to n
... """Return a list containing the Fibonacci series up to n."""
... result = []
... a, b = 0, 1
