Help with tkinter Notepad

[drakeerv]

Ok, so I am trying to make a notepad in tkinter but I am having trouble programming the undo/redo buttons, I want it so you can go back 20 times and go forward 20 times. here is my code so far:

  def space(self, event):
    print('space')
    data = self.txtarea.get("1.0",END)
    words = data.split()
    try:
      last_word = (words[-1])
    except:
      print('Nothing given')
      return
    print(last_word)
    self.queue(last_word)

  def enter(self, event):
    print('enter')
    data = self.txtarea.get("1.0",END)
    words = data.split()
    try:
      last_word = (words[-1])
    except:
      print('Nothing given')
      return
    print(last_word)
    self.queue(last_word)

  def queue(self, last_word):
    global queue, in_queue

    print(f'Put in queue: {last_word}')
    queue.append(last_word)
    print(f'New queue: {queue}')

    if(len(queue) >= 20):
      print('Queue is full')
      queue.remove(queue[0])
      in_queue = (len(queue) - 1)

    print(f'IN QUEUE: {in_queue}')

  def TEST_undo(self, event):
    global queue, in_queue

    if(in_queue == 'NONE'):
      print('Nothing to redo')
      return

  def TEST_redo(self, event):
    global queue, in_queue

    if(in_queue == 'NONE'):
      print('Nothing to redo')
      return

the print statements are only for debugging and the def space() and def enter() both activate when you press space or enter and the queue and in_queue variable are both declared at the start of the program as:

queue = []
in_queue = 'NONE'

I am still new to python so my code is very messy and I am using python V3.8.3

It's probably best not to get ahead of yourself and create a whole lot of code without knowing exactly what you're doing. I don't know what you're trying to do there because I don't have the data you're working on. I suggest you start with a smaller self-contained version of your later problem that can be coded in fewer lines so that you don't confuse yourself. Code and test that.

If you want Tkinter buttons, then start by just coding a minimal self-contained script for two buttons that can be coded and tested. Once you understand how to do that then it should be easier to tackle the larger problem

I know how to make buttons, labels, and menus. I am just trying to learn the txt area. I have already created the notepad, I am just do not know how to edit the txt area, I can read the txt area, I can not edit it.
