How Can I Display a Progress Bar in Python Using tqdm?

Displaying a Progress Bar with Python's tqdm

When executing time-consuming tasks in Python, it can be beneficial to display a progress bar to provide real-time feedback to the user. One popular and effective solution is the tqdm library.

Using tqdm

To incorporate a progress bar into your script, follow these steps:

1. Install tqdm using one of the following commands:
   
   
   
   • Conda: conda install tqdm
   
   
   • Pip: pip install tqdm
   
   


2. Import tqdm:

from tqdm import tqdm

3. Wrap your loop in a tqdm object:

for i in tqdm(range(10)):
    # Do something time-consuming...
    time.sleep(1)

This will display a progress bar that updates in real-time as the loop iterates. You can also customize the progress bar's appearance and functionality by modifying the tqdm arguments, such as desc for a custom description and bar_format for specifying the progress bar's formatting.

Additional Features

tqdm also offers several additional features:

• A notebook version (tqdm.notebook) that displays progress bars within Jupyter notebooks.
• Helper functions to enumerate, map, and zip with progress bars.
• Concurrent maps that allow for multi-threaded processing with progress updates.
• Integrations with mobile messaging platforms like Telegram and Discord to receive progress updates on your phone.
