So mine are almost identical to Tim’s but I’ll post them anyway along with the time they take…

Problem 1:

sum = 0 for i in range(1000): if (i%3 == 0 or i%5 == 0): sum = sum + i print sum

Time: 0.000477 sec

Problem 2:

fibsum = 0

a, b = 0, 1

while b < 4000000:
if b%2 == 0:
fibsum = fibsum + b
a, b = b, (a+b)
print fibsum

Time: 0.000148 sec
