In this article we will see how to make progress bar with the help of tqdm module. A progress bar is a graphical control element used to visualize the progression of an extended computer operation, such as a download, file transfer, or installation. Sometimes, the graphic is accompanied by a textual representation of the progress in a percent format.
Required Modules :
Tqdm : Tqdm package is one of the more comprehensive packages for progress bars with python and is handy for those instances you want to build scripts that keep the users informed on the status of your application.
pip install tqdmTime : This module provides various time-related functions, it is part of python’s standard library.
Example 1:
# importing modules from tqdm import trange from time import sleep # creating loop for i in trange(10, desc ="loop "): # slowing the for loop sleep(0.1) |
Output :
Example 2:
# importing modules from tqdm import tnrange from time import sleep # creating loop for i in tnrange(2, desc ="loop 1"): # creating nested loop for j in tnrange(5, desc ="loop 2"): # slowing the for loop sleep(0.2) |
Output :
Example 3:
# importing modules import time import sys from tqdm import trange # random function def random_task(): time.sleep(0.5) # another random function def another_random_task(): time.sleep(0.2) # Outer loop for i in trange(3, file=sys.stdout, desc='Outer loop'): random_task() # inner loop for j in trange(5,file=sys.stdout, desc='Inner loop'): another_random_task() |
