Hi All,

In this blog, I will tell you , how to make a simple Sign-In/Log-In UI for User. I'm using python27 for this code. Python give you IDLE, which is a good python editor. There are many libraries to make User interface in python, but i m using Tkinter which is python inbuilt library.

 Opening a simple window using Tkinter

#!/usr/bin/python

import Tkinter
top = Tkinter.Tk()
# Code to add widgets will go here...
top.mainloop()

Below code is showing simple sign in process in which username "Jagan" and password "123456" is used.

from Tkinter import *
import Tkinter as tk
class Application(Frame):
    """ GUI application which can reveal the secret of longevity. """
    def __init__(self, master):
        """ Initialize the frame. """
        Frame.__init__(self, master)
        self.grid()
        self.create_widgets()

    def create_widgets(self):
        """ Create button, text, and entry widgets. """
        
        self.userLbl = Label(self, text = "User Name ")
        self.userLbl.grid()
        self.usernameEntry = Entry(self)
        self.usernameEntry.grid(row = 0, column = 1 ,sticky = W)
        self.passwrdLbl = Label(self, text = "Password ")
        self.passwrdLbl.grid(row = 1, column = 0 ,sticky = W)
        self.passEntry = Entry(self, show="*")
        self.passEntry.grid(row = 1, column = 1 ,sticky = W)
        self.submit_bttn = Button(self, text = "LOGIN", command = self.reveal)
        self.submit_bttn.grid(row = 2, column = 1 ,sticky = W)

    def create_window(self):
        t = tk.Toplevel(self)
        t.wm_title("Status")
        l = tk.Label(t, text="LOGIN  %s" % self.Status)
        l.pack(side="top", fill="both", expand=False, padx=100, pady=100)

    def reveal(self):
       """ Display message based on password. """
       user = self.usernameEntry.get()
       password = self.passEntry.get()
       if user == "Jagan":
           if password == "123456":
               self.Status = "SUCCESSFULLY"
               self.create_window()
           else :
               self.Status = "FAILED"
               self.create_window()
       else :
           self.Status = "FAILED"
           self.create_window()

# main
root = Tk()
root.title("Sample Login UI")
root.geometry("250x150")
app = Application(root)
root.mainloop()
