You can use python tqdm module to display the progress bar for a python script or command.
Install python module tqdm using pip

## install tqdm pip install tqdm |
Usage Examples:
Iterable-based:
Wrap tqdm() around any iterable:
|
1 2 3 4 5 6 7 |
from tqdm import tqdm from time import sleep text = "" for char in tqdm(["a", "b", "c", "d"]): sleep(0.25) text = text + char |
trange(i) is a special optimised instance of tqdm(range(i)):
|
1 2 3 4 |
from tqdm import trange for i in trange(100): sleep(0.01) |
Instantiation outside of the loop allows for manual control over tqdm():
|
1 2 3 4 |
pbar = tqdm(["a", "b", "c", "d"]) for char in pbar: sleep(0.25) pbar.set_description("Processing %s" % char) |
Manual control of tqdm() updates using a with statement:
|
1 2 3 4 |
with tqdm(total=100) as pbar: for i in range(10): sleep(0.1) pbar.update(10) |
Module
Perhaps the most wonderful use of tqdm is in a script or on the command line. Simply inserting tqdm (or python -m tqdm) between pipes will pass through all stdin to stdout while printing progress to stderr.
