Running python 2.7 on Ubuntu 12.04
Code:
def fib2(n):
if n==1:
return 1
elif n==2:
return 1
else:
return fib2(n-2) +fib2(n-1)
The above works:
>>> fib2(7)
13
>>> fib2(4)
3
>>> for i in range(4):
... print fib2(i)
...
The above results in an error:
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
File "testing.py", line 21, in fib2
return fib2(n-2) +fib2(n-1)
File "testing.py", line 21, in fib2
return fib2(n-2) +fib2(n-1)
<snip>
File "testing.py", line 21, in fib2
return fib2(n-2) +fib2(n-1)
RuntimeError: maximum recursion depth exceeded
>>>
Is this some subtle problem or is it some stupid mistake on my part?
Thanks for your help.
