Enhancing Python Scripts with Alive-Progress: 5 Practical Examples

 pip install alive-progress

1. Simple Progress Bar

from alive_progress import alive_bar

import time

items = range(100)

with alive_bar(len(items)) as bar:

    for item in items:

        time.sleep(0.05)  

        bar()

|████████████████████████████████████████| 100/100 [100%] in 5.0s (19.83/s) 

2. Progress Bar with Custom Text

from alive_progress import alive_bar

import time

tasks = ['task1', 'task2', 'task3', 'task4']

with alive_bar(len(tasks), title='Processing Tasks') as bar:

    for task in tasks:

        time.sleep(0.5)  

        bar.text = f'Working on {task}'

        bar()

Processing Tasks |████████████████████████████████████████| 4/4 [100%] in 2.0s (2.00/s) 

3. Nested Progress Bars

from alive_progress import alive_bar

import time

outer_items = range(3)

inner_items = range(5)

with alive_bar(len(outer_items) * len(inner_items), title='Processing') as bar:

    for _ in outer_items:

        for _ in inner_items:

            time.sleep(0.1)  # Simulate work

            bar()

Processing |████████████████████████████████████████| 15/15 [100%] in 1.5s (9.94/s) 

4. Download Simulation with Progress Bar

from alive_progress import alive_bar

import time

file_size = 1024  

chunk_size = 64

with alive_bar(file_size // chunk_size, title='Downloading') as bar:

    for _ in range(0, file_size, chunk_size):

        time.sleep(0.1) 

        bar()

Downloading |████████████████████████████████████████| 16/16 [100%] in 1.6s (9.83/s) 

5. Progress Bar with Percentage and ETA

from alive_progress import alive_bar

import time

total_items = 50

with alive_bar(total_items, title='Processing', 

               spinner='dots_waves', bar='smooth') as bar:

    for _ in range(total_items):

        time.sleep(0.1)  

        bar()

Processing |████████████████████████████████████████| 50/50 [100%] in 5.0s (9.95/s)
