Hi folks,
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:
*import itertools*
*
*
*def fibonacci()
Thats surprising. The code runs just fine

As an aside I renamed _sum to sum_
When avoiding naming conflicts, its recommended to postfix a underscore
Prefixing an underscore is to provide a hint that the value that gets
assigned to the variable is going to be
import itertools
def fib():
a, b = 0, 1
while True:
yield b
a, b = b, a+b
print sum(itertools.takewhile(lambda x: x < 400, fib))
---
I tried the above; and it worked too (986)

Hi,
"_sum=sum([n for n in itertools.takewhile(lambda x: x < 400, fib)])
TypeError: 'int' object is not callable"
Probably 'sum' might have been used earlier in the code to store the value
of some integer. "sum" is a builtin function but the moment you assign
sum=(x+y) or something, you have lost t
