for循环

for i in range(10):
    if i >= 5:
        print(i)
    else:
        #break 跳出本层循环
        continue #跳出本次循环
        print("-----")

for i in range(10):
    print(i)
    if i== 5:
        break

else: #当循环正常结束时，走else
    print("done")

while循环

count = 0
while True:
    print("你是风儿我是沙,缠缠绵绵到天涯...",count)
    count +=1
    if count == 100:
        break

　　

跳出多层循环#跳出多层循环，while、for、if都有else分支，循环完才执行else

for i in range(3):
    for j in range(3):
        if i==j==1:
            break
        else:
            print(i,j)
    else:
        continue
    break

,,,
结果为

0 0
0 1
0 2
1 0
