Can I add message to the tqdm progressbar?
提问by Dror Hilman
When using the tqdm progress bar: can I add a message to the same line as the progress bar in a loop?
使用 tqdm 进度条时：我可以在循环中将消息添加到与进度条相同的行吗？
I tried using the "tqdm.write" option, but it adds a new line on every write. I would like each iteration to show a short message next to the bar, that will disappear in the next iteration. Is this possible?
我尝试使用“tqdm.write”选项，但它在每次写入时添加一个新行。我希望每次迭代都在栏旁边显示一条短消息，该消息将在下一次迭代中消失。这可能吗？

The example shown in Usage of tqdmworks well for me.
tqdm 的用法中显示的示例对我来说效果很好。
pbar = tqdm(["a", "b", "c", "d"])
for char in pbar:
pbar.set_description("Processing %s" % char)

You can change the description to show a small message before the progress bar, like this:
您可以更改描述以在进度条前显示一条小消息，如下所示：
from tqdm import trange
from time import sleep
t = trange(100, desc='Bar desc', leave=True)
for i in t:
t.set_description("Bar desc (file %i)" % i)
t.refresh() # to show immediately the update
sleep(0.01)
