Python – Create progress bar using tqdm module
  • Last Updated : 22 Apr, 2020

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()
