4.8. Defining Functions example is slightly misleading

[gitstashgithub]

https://docs.python.org/3/tutorial/controlflow.html#defining-functions
This is the example:

def fib(n):    # write Fibonacci series up to n
    """Print a Fibonacci series up to n."""
    a, b = 0, 1
    while a < n:
        print(a, end=' ')
        a, b = b, a+b
    print()

# Now call the function we just defined:
fib(2000)

But this example writes Fibonacci series less than n, not up to n.
