Terminal progress bar with python

The module tqdm lets you create a progress bar. This lets you make nice progress bars:

Why the name tqdm?

The developer thought it's a good name. It is an abbreviation for "I love you so much" in Spanish (te quiero demasiado).

Por favor?

Salright.

Create progress meter

Instantly make your loops show a smart progress meter - just wrap any iterable with tqdm(iterable), and you're done!

from tqdm import tqdm
    for i in tqdm(range(10000)):
        ...

Creates

76%|████████████████████████████         | 7568/10000 [00:33<00:10,      229.00it/s]

Demo

The code below creates several threads.

You see, it can be used both on the current thread and with several threads.

#!/usr/bin/python3
import time
import tqdm

def work1():
    time.sleep(1)
def work2():
    time.sleep(1)
def work3():
    time.sleep(1)
def work4():
    time.sleep(1)
def work5():
    time.sleep(1)
def work6():
    time.sleep(1)

def worker():
    work_set = [work1, work2, work3, work4, work5, work6]
    return work_set

def main():
    a = worker()
    for i in tqdm.tqdm(range(6)):
        b = a[i]()

if __name__ == '__main__':
    main()

Then:

100%|████████████████████████████████████| 6/6 [00:06<00:00,  1.00s/it]
