How to use progressbar In Python
How To Install
For command-line interface
pip install progressbar (or) pip install progressbar2
Working
It does everything the same as tqdm package, that is it decorates the iterable with the built-in widgets to make an animated progress bar or even a colorful one. Widgets are objects which display depending on the progress bar. However, the progress bar and the progress bar 2 packages have a lot of extra, useful methods than the tqdm package. For example, we can make an animated loading bar.
Python3
import progressbarimport time# Function to create def animated_marker(): widgets = ['Loading: ', progressbar.AnimatedMarker()] bar = progressbar.ProgressBar(widgets=widgets).start() for i in range(50): time.sleep(0.1) bar.update(i) # Driver's codeanimated_marker() |
Output:
In progressbar.AnimatedMarker(), we can pass any sequence of characters to animate. The default arguments are ‘|/-\|’ Here’s another example using some of the commonly used widgets of the ProgressBar class.
Python3
import timeimport progressbarwidgets = [' [', progressbar.Timer(format= 'elapsed time: %(elapsed)s'), '] ', progressbar.Bar('*'),' (', progressbar.ETA(), ') ', ]bar = progressbar.ProgressBar(max_value=200, widgets=widgets).start()for i in range(200): time.sleep(0.1) bar.update(i) |
Output:
Progress Bars in Python
Understandably, we get a little impatient when we do not know how much time a process is going to take, for example, a for loop or a file downloading or an application starting up. To distract us from that we were given the libraries tqdm and progressbar in Python language which allows us to give a visual illustration of the process completion time using a progress bar. Loading bars are often seen on game screens as the resources required for the game to run are being acquired to the main memory.
