Forgot to include the following information,
Platform - win32
Version - 2.5.1
Error message:
Traceback (most recent call last):
File "C:\Python25\programs\fibo.py", line 10, in <module>
if i % 2 == 0:
MemoryError
Code:
fib = []
even = []
def fibonacci(x,y):
return x+y
for i in range (0,1000000):
if i < 2:
fib.append(i)
else:
i = fib[i-1] + fib[i-2]
if i % 2 == 0:
fib.append(i)
even.append(i)
else:
fib.append(i)
total = reduce(fibonacci,even)
print total
Any pointers would be of great help to me.

Subject: Memory error - how to manage large data sets?
Hi,
I am new to Python programming, I was trying to work out a few problems in
order to grasp the knowledge gained after going through the basic chapters
on Python programming. I got stuck with a memory error.
Following is what I did,
1. I need to find the sum of all numbers at even positions in the
Fibonacci series upto 2 million.
2. I have used lists to achieve this.
3. My program works good with smaller ranges. Say till 10,000 or even
100,000. However when I compute the sum for bigger ranges it gives me the
memory error.
4. Also could someone tell me how to get the result in the form of an
exponent. For instance, I would prefer 10^5 rather 100000.
Thanks in advance,
Karthik
