In this Python TKinter article i want to show you How to Create ProgressBar in Python TKinter. first of let’s talk about TKinter ProgressBar, but you will have a question in your mind, that Is Tkinter the only GUI for Python? the answer is No, if you are Python developer, for creating a GUI in Python, you have different options, for example PyQt6, wxPython, PySide6 and also Kivy. so now let’s talk about progressbar in Python.
What is TKinter ProgressBar?
How to Create ProgressBar In Python TKinter?
For creating a ProgressBar in Python Tkinter, you can use ttk.Progressbar widget from the ttk module. This is a simple example of how to create and use a ProgressBar:

These are the imports that we need for this article, basically it is tkinter library, also we are going to import ttk from tkinter with time library from Python.

from tkinter import * from tkinter import ttk import time |
So at the top we have created our Root class that extends from TK, and we have added our window requirements like title, size and icon in the constructor of the class.

class Root(Tk): def __init__(self): super(Root, self).__init__() self.title("Tkinter Progress Bar") self.minsize(640, 400) self.iconbitmap('icon.ico') self.buttonFrame = ttk.LabelFrame(self, text="Progress Bars") self.buttonFrame.grid(column=0, row=0) self.progressBar() |
In this method we create three buttons with ProgressBar, and i want to give some functionality to these buttons. i want when a user click on run the progressbar should be run in the stop it should be stopped.

def progressBar(self): self.button1 = ttk.Button(self.buttonFrame, text = "Run Progress Bar", command = self.run_progressbar) self.button1.grid(column =0, row = 0) self.button2 = ttk.Button(self.buttonFrame, text = "Start Progress Bar", command = self.start_progressbar) self.button2.grid(column = 0, row = 1) self.button3 = ttk.Button(self.buttonFrame, text="Stop Immediatly", command = self.stop_progressbar) self.button3.grid(column=0, row=2) self.progress_bar = ttk.Progressbar(self, orient = 'horizontal', length = 286, mode = 'determinate') self.progress_bar.grid(column = 0, row = 3, pady =2) |
And these are the methods for the functionality of our progressbar.

def run_progressbar(self): self.progress_bar["maximum"] = 100 for i in range(101): time.sleep(0.05) self.progress_bar["value"] = i self.progress_bar.update() self.progress_bar["value"] = 0 def start_progressbar(self): self.progress_bar.start() def stop_progressbar(self): self.progress_bar.stop() |

Thanks a lot for your videos. I’ve been finally starting to understand Tkinter better after watching your videos. But there’s something I can’t manage to figure out: how do I make the progress bar stop once it reaches 100? Because in the video, it continues to move until it I press ‘stop’, but what if I wanted it to stop if it also reached the maximum value?
you can check the max size, if it goes to hundred you can make the value to zero or stop progressbar
