python - Tkinter Password System -


i'm new using tkinter in python , i'm wondering if can me password system. i'm struggling when comes checking user entered username actual username, i'm not bothered password part @ point once have got username part working should easy enough adjust code username section. anyway here code: 

#toms password system  import tkinter tkinter import * tkinter import ttk   username = ("tom") password = ("")  usernameguess1 = ("") passwordguess1 = ("")   #ignore file writing part,i'll sort out later.  file = open("userlogondata.txt", "w") file.write("user data:\n")  file = open("userlogondata.txt", "r")  def trylogin():    print ("trying login...")    if usernameguess == username:        print ("complete sucsessfull!")        messagebox.showinfo("-- complete --", "you have logged in.",icon="info")    else:        print ("error: (incorrect value entered)")        messagebox.showinfo("-- error --", "please enter valid infomation!", icon="warning")    #gui things window = tkinter.tk()  window.resizable(width=false, height=false) window.title("log-in") window.geometry("200x150") window.wm_iconbitmap("applicationlogo.ico")   #creating username & password entry boxes usernametext = tkinter.label(window, text="username:") usernameguess = tkinter.entry(window) passwordtext = tkinter.label(window, text="password:") passwordguess = tkinter.entry(window, show="*")  usernameguess1 = usernameguess     #attempt login button attemptlogin = tkinter.button(text="login", command=trylogin)    usernametext.pack() usernameguess.pack() passwordtext.pack() passwordguess.pack() attemptlogin.pack() #main starter window.mainloop()

what doing wrong doesn't allow me check if user name correct ?

you need get value entry widget:

 if usernameguess.get() == username:

you should import need , use underscores in variable names:

from tkinter import messagebox, label, button, false, tk, entry  username = ("tom") password = ("")   def try_login():     print("trying login...")     if username_guess.get() == username:         messagebox.showinfo("-- complete --", "you have logged in.", icon="info")     else:         messagebox.showinfo("-- error --", "please enter valid infomation!", icon="warning")  #gui things window = tk() window.resizable(width=false, height=false) window.title("log-in") window.geometry("200x150")  #creating username & password entry boxes username_text = label(window, text="username:") username_guess = entry(window) password_text = label(window, text="password:") password_guess = entry(window, show="*")  #attempt login button attempt_login = button(text="login", command=try_login)  username_text.pack() username_guess.pack() password_text.pack() password_guess.pack() attempt_login.pack() #main starter window.mainloop()

you never close file after opening writing there chance experience behaviour not expect, close files after finished them or better again use with open them.
