本文实例讲述了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:
|
1
2
|
|#############################---------------------|
59 percent done
|
代码如下:
|
1
2
3
4
5
6
7
8
9
|
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"):
|
1
2
3
4
5
6
7
|
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。
