Progressbar widget in Tkinter | Python Last Updated : 01 May, 2019 Comments Improve Suggest changes 20 Likes Like Report The purpose of this widget is to reassure the user that something is happening. It can operate in one of two modes - In determinate mode, the widget shows an indicator that moves from beginning to end under program control. In indeterminate mode, the widget is animated so the user will believe that something is in progress. In this mode, the indicator bounces back and forth between the ends of the widget. Syntax: widget_object = Progressbar(parent, **options) Code #1 In determinate mode Python3 1== # importing tkinter module from tkinter import * from tkinter.ttk import * # creating tkinter window root = Tk() # Progress bar widget progress = Progressbar(root, orient = HORIZONTAL, length = 100, mode = 'determinate') # Function responsible for the updation # of the progress bar value def bar(): import time progress['value'] = 20 root.update_idletasks() time.sleep(1) progress['value'] = 40 root.update_idletasks() time.sleep(1) progress['value'] = 50 root.update_idletasks() time.sleep(1) progress['value'] = 60 root.update_idletasks() time.sleep(1) progress['value'] = 80 root.update_idletasks() time.sleep(1) progress['value'] = 100 progress.pack(pady = 10) # This button will initialize # the progress bar Button(root, text = 'Start', command = bar).pack(pady = 10) # infinite loop mainloop() Output: Code #2: In indeterminate mode Python3 1== # importing tkinter module from tkinter import * from tkinter.ttk import * # creating tkinter window root = Tk() # Progress bar widget progress = Progressbar(root, orient = HORIZONTAL, length = 100, mode = 'indeterminate') # Function responsible for the updation # of the progress bar value def bar(): import time progress['value'] = 20 root.update_idletasks() time.sleep(0.5) progress['value'] = 40 root.update_idletasks() time.sleep(0.5) progress['value'] = 50 root.update_idletasks() time.sleep(0.5) progress['value'] = 60 root.update_idletasks() time.sleep(0.5) progress['value'] = 80 root.update_idletasks() time.sleep(0.5) progress['value'] = 100 root.update_idletasks() time.sleep(0.5) progress['value'] = 80 root.update_idletasks() time.sleep(0.5) progress['value'] = 60 root.update_idletasks() time.sleep(0.5) progress['value'] = 50 root.update_idletasks() time.sleep(0.5) progress['value'] = 40 root.update_idletasks() time.sleep(0.5) progress['value'] = 20 root.update_idletasks() time.sleep(0.5) progress['value'] = 0 progress.pack(pady = 10) # This button will initialize # the progress bar Button(root, text = 'Start', command = bar).pack(pady = 10) # infinite loop mainloop() Output: Create Quiz Comment S sanjeev2552 Follow 20 Improve S sanjeev2552 Follow 20 Improve Article Tags : Python Python-tkinter Python-gui Python Tkinter Widget Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
