TQDM

A module that allows you to create progress bars for iterables in python.

Usage

Requirements

For this demo you will need a few things, i've outlined the requirements below and how to set them up:

• TQDM: to get tqdm you can either use pip install tqdm or in the folder with this readme run pip install -r requirements.txt

Real World Applications

This module is incredibly useful for scripts that have any long iteration processes. For example if you are scraping contents from an HTML table on a webpage that has a few hundred entries adding a progress bar let's users (including you) know that the script/program hasn't crashed and is just taking a while to process.

tqdm_demo.py

from tqdm import tqdm # The module relies on a class called tqdm inside the module
import time # Used to delay iteration to make the progress bar more easily visible

# Un-fortmatted tqdm progress bar
print("Here is your standard tqdm bar:")

for iteration in tqdm(range(10)):
    time.sleep(.3)

# Example of a formatted tqdm bar
print("Here is a custom formatted tqdm bar:")
iterable = tqdm(range(100)) # Setting iterable wrapped in tqdm as a variable

for amount_complete in iterable: # This demo is based on https://github.com/tqdm/tqdm#iterable-based
    time.sleep(0.25)
    iterable.set_description(f"Currently at %{amount_complete}") # Allows you to overwrite the default printing style provided by tqdm
