I don’t understand why this error appears, I have two source codes in one, everything works fine, in the second this error comes out. Looked at similar questions
but it did not give a result

Firstly, when you are changing the Root Title and geometry, you do not need to call the root simply leaving it as self.master.geometry('400x300+200+200') will work fine.
Secondly, when using from tkinter import * you do not need to use tk.Frame you can just use Frame as Python will recognise this as a class name.
Thirdly one of your button commands self.safe will cause an error because this method is not defined nor is it a built in Tk command.
Improved code...

I'm having a hard time with calling the recordtable variable from my def btn3function() to my def update(). Anyone can help how I can call it without any error? Here's the full detail. I hope this will help, and thank you in advance again. I'm open to any suggestion or ideas. Willing to be enlightened.
reg = []
def register(name, number, date, time):
reg.append([name, number, date, time])
update()
def update(recordtable):
for item in recordtable.get_children():
recordtable.delete(item)
for r in range(len(reg)):
recordtable.insert(parent='', index='end', text='', iid=r, values=reg[r])
def btn3function(recordtable):
top = tkinter.Toplevel(root)
top.title("APPOINTMENTS")
frame = tk.Frame(top)
bg = ImageTk.PhotoImage(file="appointments.png")
labl = tk.Label(frame, image=bg)
labl.img = bg
labl.place(relx=0.5, rely=0.5, anchor='center')
frame.pack(pady=10)
frame.pack_propagate(False)
frame.configure(width=1000, height=790)
name = tk.Label(frame, text="Name:", font=('Bold', 16))
name.place(x=180, y=250)
nameEntry = tk.Entry(frame, font=('Bold', 16))
nameEntry.place(x=280, y=250, width=180)

recordlabel.pack(fill=tk.X)
recordlabel.place(x=350, y=500)
recordtable = ttk.Treeview(frame)
recordtable.pack(fill=tk.X, pady=5, side=BOTTOM)
recordtable['column'] = ['Name', 'Number', 'Date', 'Time']
recordtable.column('#0', anchor=tk.W, width=0, stretch=tk.NO)
recordtable.column('Name', anchor=tk.W, width=100)
recordtable.column('Number', anchor=tk.W, width=100)

recordtable.heading('Name', text="NAME", anchor=tk.W)
recordtable.heading('Number', text="NUMBER", anchor=tk.W)
recordtable.heading('Date', text="DATE", anchor=tk.W)
recordtable.heading('Time', text="TIME", anchor=tk.W)
Pass the recordtable variable into update as a parameter: def btn3function(rt). I'm not sure where you're actually calling update, but when you do you should do this: update(recordtable) somewhere after the declaration of recordtable
When I press OK to print out the answer multiple times, the answers just stack on each other but are not replaced by each other, how do I fix this bug?

It is better to create the result label once inside main() and update its text inside button2_click():

Edit: I moved the button2_click () to the top. I comment out in line 17.

You didn't pack the menu_frame and the indentation of def btncmd() was wrong.
That is:

btn3.pack()
menu_frame.pack()

I'm trying to create a program in where you put a word in a box, press add, and this word goes to a list, which is also displayed on the right side. When I press the forward button the first thing on the list is deleted. Problem is I can't get the labels to update when I press the buttons / edit the list.

If so:
You create a list and then you use the append function to add an item to it. The rest was pretty much right.
I am currently trying to build a GUI calculator using python with the help of tkinter. I have managed to set up all of my buttons and they interact with my entry() bar when I press the button (e,g: Press button 5 and 5 appears into the entry()).
The only thing left to do is actually perform the mathematical equations that appear in the entry(). For example, if I enter 5 + 5 * 2 into the entry bar, how would I make the answer appear into the entry() after it's updated? So basically all I'm asking is someone to help me make this happen!
I have provided the code below and a screenshot of the calculator. Also please don't report this as a duplicate or flag this question as a post, (I'm reasking this question because I got no help on my last one so please help a young python programmer out!). Also I'm asking you not to provide me with links because I've read every possible link on tkinter there is to read and still have no clue what I'm doing.
Here is my code:
import sys
from tkinter import *
from PIL import Image, ImageTk
#ACTIONS:
def clear():
#Action: Clears the entry().
txtDisplay.delete(0,END);
return;
def update_Entry(inputValue):
#Updates the entry when a button is pressed.
currentText = num1.get();
update = num1.set(currentText + inputValue);

For something this simple, try having this as the command for your equalButton:
