We can pack multiple if-loops and if-else within a list generators.
Here is an example :
[i*j for i in range(1,10) for j in range(1,10) if i==j ]
[1, 4, 9, 16, 25, 36, 49, 64, 81]
Another one:
noprimes = [j for i in range(2, 8) for j in range(i*2, 50, i)]
primes = [x for x in range(2, 50) if
is a fresh breeze regarding the
current scenario :)

How does it actually work ?
( ( (1 + 2) + 3) + 4) or ( ( (4 + 1) + 2 + 3)
sum( ) - sum: (sequence[, start]), so shouldn't 4 be the 'start' that's
second case ?
Note that sum(range(n), m) is equivalent to reduce(operator.add, range(n),

On the other hand, I would like to point out that to really, really improve

It can be called just once too...
def foo():

This is because AND operator short-circuits. So when 1 foo() is false, it
terminates then and there. Srinivas is correct here.
