输出进度条的图形

# pip install tqdm
from time import sleep
from tqdm import tqdm
# 这里同样的，tqdm就是这个进度条最常用的一个方法
# 里面存一个可迭代对象
for i in tqdm(range(1, 500)):
  # 模拟你的任务
  sleep(0.01)
sleep(0.5)

# pip install alive-progress
from alive_progress import alive_bar
import time
 
# retrieve your set of items
items = range(100)       
 
# declare your expected total   
with alive_bar(len(items)) as bar:  
  # iterate as usual
  for item in items:        
    # process each item
    bar()
    time.sleep(0.1)img
