就比如像下面这种循环结果，倒计时
``` python
count = 0
b = 60
while (count < b):
count += 1
n = b - count
print n
time.sleep(1)
```
如果覆盖上一次print的结果
``` python
count = 0
b = 60
while (count < b):
count += 1
n = b - count
print n
time.sleep(1)
```
如果覆盖上一次print的结果

cc7756789 OP 搞定但是先问题无法解决，就是倒计时输出会在最左边输出，如何把它禁锢在指定的区域呢？
``` def interface_show(**kwargs): print ' '*5, kwargs['title'], kwargs['artist'], kwargs['rate'], time_remain(kwargs['minutes']) def time_remain(mins): count = 0 while (count < mins): count += 1 n = mins - count time.sleep(1) sys.stdout.write("%d \r" % n,) sys.stdout.flush() if not n: return 'completed' ``` 最后输出这样的信息，最右边的是总时长，最左边的是倒计时效果。 108 <旅立ち（「はるかな旅」ストリングス·ヴァージョン）> 吉田潔 ★★★★ 205 |
