First question, did you really type it like this or did you have 
it indented? I know some mailers strip indentation...?

In Python indentation matters so it should look like:

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


If you don't have the indentatuion(spacing) as shown Python 
will get confused - and so will your readers! - and throw an error.
