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)+ "| %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)
