Input data such as date, time, phone number, credit card number, website URL, and IP number, have an associated display format. For instance, the date can be better represented in a MM/DD/YYYY format.

from tkinter import Tk, Entry, Label, StringVar, INSERT

class FormatEntryWidgetDemo:
  
  def __init__(self, root):
    Label(root, text='Date(MM/DD/YYYY)').pack()
    self.entered_date = StringVar()
    self.date_entry = Entry(textvariable=self.entered_date)
    self.date_entry.pack(padx=5, pady=5)  
    self.date_entry...
