Answer 1

For everyone who is on windows and couldn't solve the duplicating bars issue with any of the solutions mentioned here. I had to install the colorama package as stated in tqdm's known issues which fixed it.

pip install colorama

Try it with this example:

from tqdm import tqdm
from time import sleep

for _ in tqdm(range(5), "All", ncols = 80, position = 0):
    for _ in tqdm(range(100), "Sub", ncols = 80, position = 1, leave = False):
        sleep(0.01)

Which will produce something like:

All:  60%|████████████████████████                | 3/5 [00:03<00:02,  1.02s/it]
Sub:  50%|██████████████████▌                  | 50/100 [00:00<00:00, 97.88it/s]
