|#############################---------------------|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)
