本文实例讲述了python在控制台输出进度条的方法。分享给大家供大家参考。具体实现方法如下：
进度条效果如下所示:
|
1
2
|
|#############################---------------------|59 percent done |
代码如下:
|
1
2
3
4
5
6
7
8
9
|
class ProgressBar(): def __init__(self, width=50): self.pointer = 0 self.width = width def __call__(self,x): # x in percent self.pointer = int(self.width*(x/100.0)) return "|" + "#"*self.pointer + "-"*(self.width-self.pointer)+\ "|\n %d percent done" % int(x) |
Test function (for windows system, change "clear" into "CLS"):
|
1
2
3
4
5
6
7
|
if __name__ == '__main__': import time, os pb = ProgressBar() for i in range(101): os.system('clear') print pb(i) time.sleep(0.1) |
希望本文所述对大家的Python程序设计有所帮助。
