tqdm is one of my favorite general purpose utility libraries in python. It allows me to see progress of multipart processes as they happen. I really like this for when I am developing something that takes some amount of time and I am unsure of performance. It allows me to be patient when the process is going well and will finish in sufficient time, and allows me to 💥 kill it and find a way to make it perform better if it will not finish in sufficient time.

Add a simple Progress bar!


from tqdm import tqdm
from time import sleep

for i in tqdm(range(10)):
	sleep(1)

convenience

TQDM also has a convenience function called trange that wraps the range function with a tqdm progress bar automatically.


from tqdm import trange
from time import sleep

for i in trange(range(10)):
	sleep(1)

notebook support

There is also notebook support. If you are bouncing between ipython and jupyter I recomend importing from the auto module.


from tqdm.auto import tqdm
from time import sleep

for i in tqdm(range(10)):
	sleep(1)

If you are using notebooks you should enable ipython autoreload 👆
