You can use the tqdm library to easily add a progress bar to your Python for i in range(...)
loop:
Just
from tqdm import tqdm
at the top of your script and then surround range(...)
with tqdm(...)
. For example,
mysum = 0 for i in range(50): sum += i
becomes
mysum = 0 for i in tqdm(range(50)): mysum += i
