tqdm 这么有牌面的库，竟然没没有介绍？
用起来非常的简单，也非常的好用。
一个基本的实例
# coding=utf-8
import time
from tqdm import trange, tqdm
for i in trange(10):
time.sleep(0.1)
for i in tqdm(range(100)):
time.sleep(0.1)
一个常见的示例
# coding=utf-8
import time
import random
from tqdm import tqdm
count = 0
total = 1024
progress = tqdm(total=total, unit='B',unit_scale=True, desc='filename')
while count < total:
time.sleep(1)
step = random.randrange(100)
count += step
progress.update(step)
progress.close()
也很有意思
>>> import alive_progress
>>> alive_progress.showtime()
