Progress Bar in Python

tqdm

The tqdm package in Python provides a fast, extensible progress bar for loops and other iterable objects. It was used in pip intall. Here’s a simple example:

from tqdm import tqdm
import time

# Create a list of numbers
numbers = range(100)

# Wrap your iterable with tqdm()
for i in tqdm(numbers):
    # Simulate some work
    time.sleep(0.01)

rich

from rich.progress import track
import time

# Create a list of numbers
numbers = range(100)

# Wrap your iterable with track()
for i in track(numbers, description="Processing..."):
    # Simulate some work
    time.sleep(0.01)

track() works similarly to tqdm’s wrapper. It takes an iterable and a description for the task, and returns an iterator that produces the same values as the original, but also updates a progress bar in the console as it iterates over the items.

The description parameter allows you to set a text description for the task that is displayed next to the progress bar.

Like tqdm, rich offers a variety of options to customize the appearance and behavior of the progress bar. You can find more details in the rich documentation.

    time.sleep(0.1)
