Tkinter creates login registration interface, tkinter Interface

Import tkinter as tkfrom tkinter import messagebox # Set the window center def window_info (): ws = window. winfo_screenwidth () hs = window. winfo_screenheight () x = (ws/2)-200 y = (hs/2)-200 print ("% d, % d" % (ws, hs) return x, y # Set the login window attribute window = tk. tk () window. title ('Welcome to the parking lot billing system ') a, B = window_info () window. geometry ("450x300 + % d" % (a, B) # The Information tk on the logon page. label (window, text = "parking lot Charging System", font = ("", 32 )). place (x = 80, y = 50) tk. label (Window, text = "account :"). place (x = 120, y = 150) tk. label (window, text = "Password :"). place (x = 120, y = 190) # display the input box var_usr_name = tk. stringVar () # display the default account var_usr_name.set ('000000') entry_usr_name = tk. entry (window, textvariable = var_usr_name) entry_usr_name.place (x = 190, y = 150) var_usr_pwd = tk. stringVar () # Set the password to entry_usr_pwd = tk. entry (window, textvariable = var_usr_pwd, show = '*') entry_usr_pwd.place (x = 190, y = 190) # login function def usr_log In (): # obtain the input account password usr_name = var_usr_name.get () usr_pwd = var_usr_pwd.get () # obtain the storage account information.

This is the login registration interface I wrote. Using tkinter, you can easily log on to and register an account, using the Label, Entry, and Button components.
