from tkinter import * win=Tk() var = StringVar() l = Label(win, bg='white', width=15) l.grid(row=17,column=1,padx=10, pady=10, sticky='w') def print1_selection(): if var.get()=="Number": lab1= Label(win, text="Enter a number").grid(row=4, column=0) ent1=Entry(win).grid(row=4, column=1) l.config(text='you have selected ' + var.get()) elif var.get()=="Alphabet": lab21= Label(win, text="Enter an alphabet").grid(row=5, column=0) ent21=Entry(win).grid(row=5, column=1) l.config(text='you have selected ' + var.get()) lbl4=Label(win, text="Select One", bg="crimson", fg="white", font=("times new roman",15,"bold")).grid(row=1, column=0, padx=10, pady=10, sticky='w') r1 = Radiobutton(win, text='Number',variable=var, value='Number', command=print1_selection, width=22) r1.grid(row=2,column=0,padx=10, pady=10) r2 = Radiobutton(win, text='Alphabet', variable=var, value='Alphabet', command=print1_selection, width=22) r2.grid(row=2,column=1,padx=10, pady=10) win.mainloop()
In this code I want that when I select radiobutton
number, only enter a number should appear and same for the other.
But the problem is that when I select number after selecting alphabet, it shows both. I need only the selected one and eliminate the other instantly.

This is how I would approach this issue:
from tkinter import Tk, StringVar, Label, Frame, Entry, Radiobutton def print1_selection(): for widget in entry_frame.winfo_children(): widget.destroy() value = var.get() lbl.config(text='You have selected ' + value) if value == "Number": Label(entry_frame, text="Enter a number").grid(row=0, column=0) Entry(entry_frame).grid(row=0, column=1) elif value == "Alphabet": Label(entry_frame, text="Enter an alphabet").grid(row=0, column=0) Entry(entry_frame).grid(row=0, column=1) win = Tk() var = StringVar(value=0) entry_frame = Frame(win) entry_frame.grid(row=2, column=0, columnspan=2) lbl = Label(win, bg='white', width=20) lbl.grid(row=3, column=0, columnspan=2, padx=10, pady=10, sticky='w') Label(win, text="Select One", bg="crimson", fg="white", font=("times new roman", 15, "bold")).grid(row=0, column=0, padx=10, pady=10, sticky='w') Radiobutton(win, text='Number', variable=var, value='Number', command=print1_selection, width=22).grid(row=1, column=0, padx=10, pady=10) Radiobutton(win, text='Alphabet', variable=var, value='Alphabet', command=print1_selection, width=22).grid(row=1, column=1, padx=10, pady=10) win.mainloop()
As You can see if You don’t plan on using the widgets instance anywhere You don’t have to assign it to a variable. Also no need to configure label in both statements since that will be done anyways so just do it at the beginning, also rows start from 0 too. Frames help with organizing widgets. Also if You want neither of the radiobuttons selected set the variable to 0.
