Python命令行动态进度条库：alive-progress

alive-progress是一个有着非常绚丽动画的实时进度条库。相比tqdm，python-prompt-toolkit的Progress bars等进度条库，有着更佳好看的动画界面，让人欲罢不能。

from alive_progress import alive_bar
import time

for x in 1000, 1500, 700, 0:
   with alive_bar(x) as bar:
       for i in range(1000):
           time.sleep(.005)
           bar()

** 输入结果
