break 和 continue

1.break
(1)

num = 1
while num <= 5:
    print('输入当前值:',num)
    if num ==3:
        break
    num+=1
print('程序结束。。')

(2)

for i in range(5):
    print('输入当前值:',i)
    if i==3:
        break

print('程序结束')

2. continue
(1)正常情况

num = 0
while num <= 5:
    num+=1
    if num==3:
        continue
    print("输入当前值：",num)

异常情况：

num = 0
while num <=5:
    print('输入当前值：',num)
    if num == 3:
        continue
    num+=num

（2）

for i in range(5):
    if  i == 2 :
        continue
    print(i)
