Sometime you need to make a script or a program with some task and show to the user you are doing something so you need to write something as output: a Progress Bar.
You have multiple way to do it and now I will show some way to do it with packages.
The first package I present is progress , an easy python package with a lot of configuration.
This package is base of one object, the Bar, and you set it, you use it for update the progressbass or end it.
You have this base code:
from time import sleep for i in range(100): sleep(1) print(i)
This code print the first 100 number one for row. If I want to use a progress’s progress bar I need to to something like this:
from time import sleep from progress.bar import Bar bar = Bar('Processing', max=20) for i in range(100): sleep(1) print(i) bar.next() bar.finish()
This is a base version of the code for a bar but you can add a lot of configs like suffix, max value, remaing and other things.1
This is a package wich use iterators for working. You can also create custo widgets (or bars) for creating your custom expirences.
Using the example code
from time import sleep import progressbar for i in progressbar.progressbar(range(100)): sleep(1) print(i)
you can have a progress bar using an iterator. If you need to edit the navbar you can make a custom widgets like the next example
from time import sleep import progressbar widgets=[ ' [', progressbar.Timer(), '] ', progressbar.Bar(), ' (', progressbar.ETA(), ') ', ] for i in progressbar.progressbar(range(100), widgets=widgets): sleep(1) print(i)
This is a custom output for the progress bar following the docs find in the project documentation2
THe fastest one for install and a very easy one.
Not huge for the customizing part but a good one. It also skip unnecessary iteration displays.
Allwayse with our lovely code:
from time import sleep from tqdm import tqdm for i in tqdm(range(100)): sleep(1) print(i)
Here3 for the docs.
This is the fancy package for progress bar.
If you need a fancy progress bar this is the best one.
With our favorite example this is an example
from time import sleep from alive_progress import alive_bar items = range(100) with alive_bar(len(items)) as bar: for i in items: sleep(1) print(i) bar()
With the correct config4 you can have some of the best animation ever.
Wich progress bar is your favorite?
