The `tqdm` module is used to add progress bars to loops in Python. It provides a simple way to add a progress meter to any iterable object, such as a list, tuple, or iterator. The progress bar updates in real time as the loop executes, giving the user an estimate of how much time is remaining until completion. The module can be installed using pip by running `pip install tqdm`.
Here is an example of how `tqdm` can be used:
```
from tqdm import tqdm
my_list = [1, 2, 3, 4, 5]
for item in tqdm(my_list):
# do something with the item
```
In this example, the `tqdm` function is called with the iterable object `my_list`. As the loop iterates over the items in `my_list`, `tqdm` displays a progress bar showing the percentage of items that have been processed, along with an estimate of the time remaining until completion.
