python 在控制条输出进度条
A ”progress bar” that looks like:
|#############################---------------------| 59 percent done
Code:
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)
