If you need to get a little bit of text from a user, like a name or an email address or a contact number then use an Entry widget. Specify the position of Entry widget within the parent window e.In this tutorial, we will cover the entry widget of Tkinter in Python with its various options, and with the help of Few Examples, we will understand the concept in detail.This method is used to create the Entry widget on the parent widget (root). Return Value: Returns a string (.!entry). options: The supported options are bg, bd, command, cursor, font, exportselection, justify, relief, highlightcolor, fg, selectbackground, selectforeground, selectborderwidth, show, xscrollcommand, state, textvariable and width.master: Represents the parent window (here root).This method creates a parent widget which usually is the main window of an application. Parameter: In this example, Tk class is instantiated without arguments. Syntax: Tk(screenName=None, baseName=None, className=’Tk’, useTk=1)

However for any non-numeric input the callback function returns false. For deletion operation the callback function returns true as input is “”. If the input is numeric type then the callback function returns true. In this example, the input entered through the keyboard is checked for numeric type. If the entry is valid it returns True else False. The callback function checks the input in the Entry widget for valid entry. Define the “callback” function def callback(input):.Import tkinter submodules from tkinter import *.Python Tkinter – Validating Entry Widget.
