Python – Create progress bar using tqdm module

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 tqdm
Time : 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()
