Making Progress Bars in Python

Progress bars are an indispensable element of any project that involves time-consuming tasks, such as downloading large files or performing computations. They help keep track of the progress and provide a visual feedback to the user. In Python, progress bars can be created using the tqdm library.

The tqdm library allows you to easily create progress bars with just a few lines of code. To start using it, you need to first import the library:

import tqdm

Then, you can create a progress bar using the tqdm function. The following example creates a progress bar that goes from 0 to 100 in increments of 10:

for i in tqdm(range(0, 100, 10)):
    # Do something
    pass

The progress bar will look like this:

0%|          | 0/10 [00:00<?, ?it/s]
10%|█         | 1/10 [00:00<00:02,  2.41it/s]
20%|██        | 2/10 [00:00<00:02,  2.53it/s]
30%|███       | 3/10 [00:00<00:02,  2.59it/s]
40%|████      | 4/10 [00:00<00:02,  2.63it/s]
50%|█████     | 5/10 [00:01<00:01,  2.66it/s]
60%|██████    | 6/10 [00:01<00:01,  2.68it/s]
70%|███████   | 7/10 [00:01<00:01,  2.70it/s]
80%|████████  | 8/10 [00:01<00:00,  2.72it/s]
90%|█████████ | 9/10 [00:02<00:00,  2.74it/s]
100%|██████████| 10/10 [00:02<00:00,  2.76it/s]

The progress bar shows the progress of the task as a percentage, as well as the current iteration and the estimated time remaining. The progress bar will be updated after each iteration.

In addition to the basic progress bar, the tqdm library provides several other features that can be used to customize the progress bar. For example, you can add a description to the progress bar using the desc keyword argument. The following example adds a description to the progress bar:

for i in tqdm(range(0, 100, 10), desc="Downloading files"):
    # Do something
    pass

The output of the progress bar will look like this:

Downloading files: 0%|          | 0/10 [00:00<?, ?it/s]
Downloading files: 10%|█         | 1/10 [00:00<00:04,  1.98it/s]
Downloading files: 20%|██        | 2/10 [00:00<00:03,  2.33it/s]
Downloading files: 30%|███       | 3/10 [00:00<00:02,  2.68it/s]
Downloading files: 40%|████      | 4/10 [00:01<00:01,  2.90it/s]
Downloading files: 50%|█████     | 5/10 [00:01<00:01,  3.04it/s]
Downloading files: 60%|██████    | 6/10 [00:01<00:01,  3.11it/s]
Downloading files: 70%|███████   | 7/10 [00:02<00:00,  3.15it/s]
Downloading files: 80%|████████  | 8/10 [00:02<00:00,  3.18it/s]
Downloading files: 90%|█████████ | 9/10 [00:02<00:00,  3.20it/s]
Downloading files: 100%|██████████| 10/10 [00:02<00:00,  3.22it/s]

The tqdm library also supports other features, such as the ability to set the total number of iterations, the minimum and maximum values, the initial value, and more. For more information, please refer to the official documentation at https://pypi.org/project/tqdm/.

In conclusion, progress bars are a great way to show progress and provide feedback to users. The tqdm library makes it easy to create progress bars in Python with just a few lines of code. With its many features, you can customize the progress bar to suit your needs.
