while循环应用

1. 计算1~100的累积和(包含1和100)

参考代码如下:

#encoding=utf-8

i = 1
sum = 0
while i<=100:
    sum = sum + i
    i += 1

print("1~100的累积和为:%d"%sum)

2. 计算1~100之间偶数的累积和(包含1和100)

参考代码如下:

#encoding=utf-8

i = 1
sum = 0
while i<=100:
    if i%2 == 0:
        sum = sum + i
    i+=1

print("1~100的累积和为:%d"%sum)
