In this Python Tutorial I show you how you can add a Progress Bar to your Python code in just one line of code! We use the great tqdm module for this that can simply be installed with pip install tqdm. I show you the iterable based and the manually controlled approach.

`tqdm can be found on GitHub.
The code from this Tutorial can also be found on GitHub.

Installation¶

pip install tqdm

Iterable based approach¶

from tqdm import tqdm, trange
import time

for i in tqdm([1, 2, 3, 4, 5]):
    time.sleep(0.2)

print('done')

Special optimised instance of tqdm(range(i))¶

for i in trange(10):
    time.sleep(0.1)

print('done')

Manual approach 1: Use a with statement¶

# we can provide the optional 'total' parameter
with tqdm(total=100) as pbar:
    for i in range(10):
        time.sleep(0.1)
        pbar.update(10)

print('done')

Manual approach 2: Assign to a variable¶

Dont forget to call close() at the end!!!

pbar = tqdm(total=100)
for i in range(10):
    time.sleep(0.1)
    pbar.update(10)
pbar.close()

print('done')
