python在控制台输出进度条的方法

本文实例讲述了python/' target='_blank'>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:

|#############################---------------------|59 percent done

代码如下:

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"):

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。
