我这个累加的码哪里错了？

print "let's gaosi"
a = 1
b = a
answer = b
while a <= 100:
    a = a + 1
    b = b + a
print answer

谢谢

a和b初始值都应该是0

而且answer = b去掉
最后print b

而且，应该小于100

print "let's gaosi"
a = 0
b = 0
while a <100:
    a = a + 1
    b = b + a
print b

按照你的改的

应该吧answer = b 这行放到while里面 最后一行，不然answer = b 等于的还是在while之前的b值 也就是1
