[BangPypers] Issue with list comprehension

I am new to Python (have been on Java for 8 years), but I have quickly
grasped its style.
While working on a problem (as Python practice) to generate fibonacci
numbers using generators and list comprehension, I ran into an issue.
Here's my code:
* a, b = 0, 1*
* while True:*
* yield b*
* a, b = b, a+b*
*_sum=sum([n for n in itertools.takewhile(lambda x: x < 400, fib)])*
Basically, I wanted to sum up all the fib numbers till 400.
*This code runs fine when run on REPL (shell). But when I run it*
*as a script, i get following error:*
Traceback (most recent call last):
File "2.py", line 10, in <module>
_sum=sum([n for n in itertools.takewhile(lambda x: x < 400, fib)])
TypeError: 'int' object is not callable
Python version: 2.7.3
Is there a bug in Python or am I missing something? Why does this only work
and not as shell script?
Thanks for help.
