Python Progress Bar

Question

How do I use a progress bar when my script is doing some task that is likely to take time?

For example, a function which takes some time to complete and returns

You can use tqdm:

from tqdm import tqdm

with tqdm(total=100, desc="Adding Users", bar_format="{l_bar}{bar} [ time left: {remaining} ]") as pbar:
    for i in range(100):
        time.sleep(3)
        pbar.update(1)

In this example the progress bar is running for 5 minutes and it is shown like that:

Adding Users:   3%|█████▊                                     [ time left: 04:51 ]                                                                                                        

You can change it and customize it as you like.
