Quick run down of my program, it is an app (or box) that is supposed to help you learn Morse code. So the issue I'm having at the moment is I'm wanting to remove (destroy) a TopLevel window before a new one is created and my attempt at doing this is at the command=lambda: newwin.destroy() code in the newword function. Sorry for the lack of organisation and bad variable/function names I'm a few months into coding. 

from tkinter import *
import winsound
import random

window = Tk()
window.resizable(0, 0)
window.title("Morse Code")
frequency = 860
longbeep = 750
shortbeep = 350
window.geometry("270x130+0+0")
translate = list("")
samplewords = [""]
morsecodelist = [""] # My word lists are 1000 words long each so this post would be over the limit


def firstbuttoncmd():
    firstbutton.grid_forget()
    secondbutton.grid_forget()
    window.geometry("640x350")
    short = Button(text="Short Beep\n.", height=16, width=36, command=lambda: fpshortcmd())
    long = Button(text="Long Beep\n___", height=16, width=36, command=lambda: fplongcmd())
    short.grid(row=10, column=1)
    long.grid(row=10, column=10)
    cheatsheet = Label(
        text="A .__      U ..__\nB __...      V ...__\nC __.__.      W .__ __\nD__..      X__..__\nE .      Y __.__ __\nF ..__.

    cheatsheet.grid(row=10, column=12)

    def wordgenerator():
        newwin = Toplevel(window)
        newwin.resizable(0, 0)
        global newwin
        newwin.geometry("140x100+640+0")
        wordchoice = (random.randint(0, len(samplewords)))
        randomword = Label(newwin, text="Your Word is '" + samplewords[wordchoice - 1] + "'")
        randomword.grid()
        resetword = Button(newwin, text="             Check             ", command=lambda: newword())
        resetword.grid()

        def newword():
            stuff = "".join(translate)
            if stuff in morsecodelist:
                newwin.geometry("740x100+640+0")
                correct = Label(newwin, text="You Spelt " + "'" + samplewords[wordchoice - 1] + "'" + " Correct")
                randomword.grid_forget()
                resetword.grid_forget()
                correct.grid()
                next = Button(newwin, text="Next", command=lambda: newwin.destroy(), wordgenerator())
                next.grid()
            else:

                next = Button(newwin, text="Next", command=lambda: newwin.destroy(), wordgenerator())

  • I can see 2 problems right away. One is your lambda in the `next` buttons. This lambda needs parentheses around the method and function call like this `(newwin.destroy(), wordgenerator())` and a bigger issues is your `global newwin`. You define `newwin` before you say it is in global and this wont work. Move `global newwin` to the first line under `wordgenerator()`. – Mike - SMT Dec 04 '18 at 13:44
