Read MoreAverage Speed Calculator using Tkinter
In this article, we will create a GUI-based application that calculates the average speed of a moving object. The average speed can be calculated using the following formula: Average Speed = Distance / [Hours + (Minutes/60)] We will use Tkinter's Spinbox widget to create input controls for Distance (Kilometers), Hours, and Minutes. The Spinbox allows users to select values from a defined range using up/down arrows. Complete Example from tkinter import * # Create an instance of tkinter frame win = Tk() # Set the geometry and resize the frame win.geometry("700x400") ...

To display the Captured input, we can either print the message on the screen or display the input with the help of the Label widget.Example#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame win= Tk() #Set the geometry of Tkinter frame win.geometry("750x250") def display_text(): global entry string= entry.get() label.configure(text=string) ...
Read MoreGet contents of a Tkinter Entry widget
An Entry widget is a basic one-line character widget that supports only single-line text input. An Entry widget can be defined by initializing the Entry(parent, width) constructor.To validate the Entry widget, we can use the get() method which results in the character entered in the Entry widget.Let us define an Entry widget that accepts single-line text input, and we will print the character that is input in the Entry widget.Example#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame win = Tk() #Set the geometry of Tkinter frame win.geometry("750x250") def get_content(): ...
Read MoreSave File Dialog Box in Tkinter
