tqdm: extract time passed + time remaining?

Question

I have been going over the tqdm docs, but no matter where I look, I cannot find a method by which to extract the time passed and estimated time remaining fields (basically the center of the progress bar on each line: 00:00<00:02).

 0%|          | 0/200 [00:00<?, ?it/s]
  4%|▎         | 7/200 [00:00<00:02, 68.64it/s]
  8%|▊         | 16/200 [00:00<00:02, 72.87it/s]
 12%|█▎        | 25/200 [00:00<00:02, 77.15it/s]
 17%|█▋        | 34/200 [00:00<00:02, 79.79it/s]
 22%|██▏       | 43/200 [00:00<00:01, 79.91it/s]
 26%|██▌       | 52/200 [00:00<00:01, 80.23it/s]
 30%|███       | 61/200 [00:00<00:01, 82.13it/s]
....
100%|██████████| 200/200 [00:02<00:00, 81.22it/s]

tqdm works via essentially printing a dynamic progress bar anytime an update occurs, but is there a way to "just" print the 00:01 and 00:02 portions, so I could use them elsewhere in my Python program, such as in automatic stopping code that halts the process if it is taking too long?

Answer 1

tqdm objects expose some information via the public property format_dict.

from tqdm import tqdm

with tqdm(total=100) as t:
    ...
    t.update()
    print(t.format_interval(t.format_dict['elapsed']))

Otherwise you could parse str(t).split()

Answer 2

You can get elapsed and remaining time from format_dict and some calculations.

t = tqdm(total=100)
...
elapsed = t.format_dict["elapsed"]
rate = t.format_dict["rate"]
remaining = (t.total - t.n) / rate if rate and t.total else 0  # Seconds*
