解决方案有两个.

1. 转到编辑配置".单击正在使用的运行/调试配置.应该有一个选项在输出控制台中模拟终端".检查那个.添加图片以供参考.

1. Go to "Edit configurations". Click on the run/debug configuration that is being used. There should be an option "Emulate terminal in output console". Check that. Image added for reference.

与 position 参数一起，还设置 leave 参数.代码应如下所示.我添加了 ncols 以便进度条不会占据整个控制台.

Along with the position argument also set the leave argument. The code should look like this. I have added ncols so that the progress bar doesn't take up whole of the console.

from tqdm import tqdm
import time

for i in tqdm(range(5), position=0, desc="i", leave=False, colour='green', ncols=80):
    for j in tqdm(range(10), position=1, desc="j", leave=False, colour='red', ncols=80):
        time.sleep(0.5)

现在运行代码时，控制台的输出如下图所示.

When the code is now run, the output of the console is as shown below.

i:  20%|████████▍                                 | 1/5 [00:05<00:20,  5.10s/it]
j:  60%|████████████████████████▌                | 6/10 [00:03<00:02,  1.95it/s]
