tqdm

tqdm

• 写法一
  缺点：多了一层缩进

with tqdm(total=len(a), desc='test_round', unit='round') as pbar:
    for i in a:
        # print(i)
        pbar.update(1)
        pbar.set_postfix({"finished": f"{i+1}"})
        # pbar.set_postfix_str(f"finished:{i+1}")
        time.sleep(1)

>>> test_round: 100%|██████████| 10/10 [00:10<00:00,  1.01s/round, finished=10]

• 写法二
  缺点：暂时没找到可以（像方法一中的set_postfix）动态更新自定义信息的办法

for i in tqdm(a, desc='test_round', unit='round'):
    time.sleep(1)

>>> test_round: 100%|██████████| 10/10 [00:10<00:00,  1.01s/round]

• 写法三
  效果同写法一，但少一层缩进
  缺点：要手动删除 tqdm()对象

tmp_pbar = tqdm(a, desc='test_round', unit='round')
for i in tmp_pbar:
    tmp_pbar.set_postfix_str(f"finished:{i+1}")
    time.sleep(1)
del tmp_pbar
