python - 使用多个条

Question

我想要两个独立的进度条。

这是一个最小的例子，如果我使用两个柱，它们不会正确更新。相反，会创建新的条。

import time
from tqdm import *

pbar1 = tqdm(total=100)
pbar2 = tqdm(total=200)

for i in range(10):
    pbar1.update(10)
    pbar2.update(20)
    time.sleep(1)

运行示例时。我得到类似的东西:

  0%|          | 0/100 [00:00<?, ?it/s]
 20%|██        | 20/100 [00:01<00:04, 19.97it/s]
 30%|███       | 30/100 [00:02<00:04, 15.36it/s]
 40%|████      | 40/100 [00:03<00:04, 13.23it/s]
 50%|█████     | 50/100 [00:04<00:04, 12.05it/s]
 60%|██████    | 60/100 [00:05<00:03, 11.35it/s]
 70%|███████   | 70/100 [00:06<00:02, 10.90it/s]
 80%|████████  | 80/100 [00:07<00:01, 10.61it/s]
 90%|█████████ | 90/100 [00:08<00:00, 10.42it/s]
100%|██████████| 100/100 [00:09<00:00, 10.28it/s]
100%|██████████| 200/200 [00:09<00:00, 20.57it/s]

如图所示，更新无法正常工作并添加了新的条。是否可以有两个独立的条正确更新？

Answer 1

尝试在初始化柱时使用 position 参数:

pbar1 = tqdm(total=100, position=1)
pbar2 = tqdm(total=200, position=0)

来自tqdm GitHub page :

position : int, optional

Specify the line offset to print this bar (starting from 0) Automatic if unspecified. Useful to manage multiple bars at once (eg, from threads).
