Hi Mark,

are you deliberately trying to break a butterfly on the wheel?

try this:

------ cut here --------
#!/usr/local/bin/python

import time

def fib(x):
    if x == 0 or x == 1:
        return 1
    else:
        return fib(x-1) + fib(x-2)

i=1
t=time.time()
while(time.time()-t<5):
    print "%d: %d" % (i, fib(i))
    i += 1

-------- cut ---------

HTH
