Please post in text, not html. Your posting program loses the
indentation in the text view, which is what most people
see.
Code:
def fib2(n):
if n==1:
return 1
elif n==2:
return 1
else:
return fib2(n-2) +fib2(n-1)
That code doesn't do anything reasonable for zero or negative
values. Probably what you want is
if n==0:
return 0
elif n <3:
return 1
else:
It would probably be technically correct to raise an exception for
n < 1, because fibonacci didn't define earlier values. But it's
apparently acceptable to return zero for the zero
case.
