python 在控制条输出进度条

A&nbsp”progress&nbspbar”&nbspthat&nbsplooks&nbsplike:

|#############################---------------------|
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&nbspfunction&nbsp(for&nbspwindows&nbspsystem,&nbspchange&nbsp”clear”&nbspinto&nbsp”CLS”):

if __name__ == '__main__':
    import time, os
    pb = ProgressBar()
    for i in range(101):
        os.system('clear')
        print pb(i)
        time.sleep(0.1)
