def func(x,*y):
    print("type=%s,x=%d"%(type(x),x))
    for i in range(len(y)):
        print("type={0},y[{1}]={2}".format(type(y[i]),i,y[i]))

    print("for语句正常结束！")
    exit()

i = 0
while(i < 10):
    print(i)
    if(i == 5):
        break#while语句非正常退出
    i += 1

    print("while正常结束")
    exit()
print("while非正常结束")

func(1,[1,"a"],25.8,"A")
print("\n")
func(8,"ascii",250,25.0,0.25e+5)

运行结果：
