[Tutor] Tkinter GUI crashing problem

[myles broomes]

Im working the Tkinter and I'm having a problem with the GUI I made. It crashes whenever I hit the submit button. Heres my code:



#Guess my number 2.0
#The guess my number game but using a GUI

 

import random
from tkinter import *


class Application(Frame):
        """GUI to hold widgets. """
        def __init__(self,master):
                super(Application,self).__init__(master)
                self.grid()
                self.createWidgets()

 

        def createWidgets(self):
                """GUI widgets. """
                #Label instructing the user to take a guess
                Label(self,text="Take a guess:").grid(row=0,column=0)

                #Entry widget where the user makes a guess
                self.guess_ent = Entry(self)
                self.guess_ent.grid(row=1,column=0)

                #Button that updates the text box
                self.submit_bttn = Button(self,command=self.update_txt,text="Submit guess")
                self.submit_bttn.grid(row=2,column=0)

                #Text box to update the user on whether their guess is correct
                self.txt_box = Text(self,width=35,height=5,wrap=WORD)
                self.txt_box.grid(row=3,column=0)

 

        def update_txt(self):
                """Updates the text box widget. """
                #Get user input from the entry widget
                number = random.randint(1,100)
                message = ""
                guess = None
                while self.guess_ent.get():
                        guess = self.guess_ent.get()
                        if int(guess) > number:
                                message += "Lower..."
                                self.txt_box.delete(0.0,END)
                                self.txt_box.insert(0.0,message)
                        else:
                                message += "Higher..."
                                self.txt_box.delete(0.0,END)
                                self.txt_box.insert(0.0,message)
                                
                if int(guess) == number:
                        message += "Congrarulations! You guessed correctly! A new number has been generated."
                        self.txt_box.delete(0.0,END)
                        self.txt_box.insert(0.0,message)

 

#main
root = Tk()
root.title("Guess my number")
app = Application(root)
root.mainloop()

 

Its frustrating because I dont even get an error code. I coded the last function in a seperate program without a GUI and it runs fine so I have no clue what the problem can be. Any help would be much appreciated.
