前言:python的break会终止整个程序,但是continue只会终止循环,让我们一起看看吧.

求0-100的奇数之和

#!/usr/bin/env python

counter = 0
sum100 = 0

while counter < 100:
    counter += 1
    if counter % 2 == 0:
        continue
    sum100 += counter

print sum100

求0-100的偶数之和

#!/usr/bin/env python

counter = 0
sum100 = 0

while counter < 100:
    counter += 1
    if counter % 2:               //前边还可以加not,计算的就是奇数和,非0为真
        continue
    sum100 += counter

print sum100

注:python非空为真,非0为真
