Append combobox values from textbox using a button

Using Python I have created a frame with empty ComboBox, TextBox and a Button. My ComboBox values are taken from List acitivity_list which initialy is empty. I am looking for a solution where user can insert a text into a TextBox and append the List activity_list so it appears in ComboBox by clicking the Button.
I failed implementing the append() function to update the List. My goal is to have a functionality where I write the name of activity in the TextBox, click the 'Add' Button and it appears in my ComboBox.
Thank you.
from tkinter import *
from tkinter import ttk
class Activity:
def __init__(self,root):
self.root=root
self.root.title("database")
self.root.geometry("1350x700+0+0")
title=Label(self.root, text="Daily Activities Database", font=("Calibri",40,"bold"))
title.pack(side=TOP)
#ComboBox
activity_list = []
Frame1=Frame(self.root,bd=4, relief=RIDGE)
Frame1.place(x=20, y=75, width=355, height=560 )
combo_activity=ttk.Combobox(Frame1, font=("Calibri",20))
combo_activity["values"]= activity_list
combo_activity.grid(row=10, column=1, padx=20, pady=10)
#Textbox
txt_act=Entry(Frame1, font=("Calibir",20))
txt_act.grid(row=11, column=1, padx=20, pady=20)
#Button
bt1 = ttk.Button(Frame1, text = "Add")
bt1.grid(row=12, column=1, padx=20, pady=20)
root=Tk()
ob=Activity(root)
root.mainloop()

Add an instance method which is triggered when Add is clicked. In the function, add the user input into activity_list and then update the values option of combo_activity.
However, you need to change some local variables to instance variables, otherwise they cannot be accessed inside the new function:
from tkinter import *
from tkinter import ttk
class Activity:
def __init__(self, root):
self.root = root
self.root.title("database")
self.root.geometry("1350x700+0+0")
title=Label(self.root, text="Daily Activities Database", font=("Calibri",40,"bold"))
title.pack(side=TOP)
Frame1 = Frame(self.root,bd=4, relief=RIDGE)
Frame1.place(x=20, y=75, width=355, height=560 )
#ComboBox
self.activity_list = []
self.combo_activity = ttk.Combobox(Frame1, font=("Calibri",20))
self.combo_activity["values"] = self.activity_list
self.combo_activity.grid(row=10, column=1, padx=20, pady=10)
#Textbox
self.txt_act = Entry(Frame1, font=("Calibir",20))
self.txt_act.grid(row=11, column=1, padx=20, pady=20)
#Button
bt1 = ttk.Button(Frame1, text="Add", command=self.add_activity) # added command option
bt1.grid(row=12, column=1, padx=20, pady=20)
def add_activity(self):
activity = self.txt_act.get().strip()
if activity:
self.activity_list.append(activity)
self.combo_activity["values"] = self.activity_list
root = Tk()
ob = Activity(root)
root.mainloop()

Thank you for help. I have adjusted the code like this and the button disappeared for the frame. Perhaps there is something wrong with indentation?
from tkinter import *
from tkinter import ttk
class Activity:
def __init__(self,root):
self.root=root
self.root.title("database")
self.root.geometry("1350x700+0+0")

return activity_list

How to hide a part of the frame through button pressing

I have a window with two parts. One part is to do some settings. I want to hide it until the user press a setting button. is it possible to hide a part of the frame that contains many widgets?
I have seen many examples to hide a widget in tkinter (eg. pack_forget and grid_forget). In my case, I am trying to hide a part of the frame through a button press (that contains more than one widgets). Any suggestions please
I can't use more than one frames because of some issues.
import tkinter as tk
def startFn():
pass
#fn body
def stopFn():
pass
#fn body
def FnToShow():
pass
#fn body ???
def FnToHide():
pass
#fn body ???
root = tk.Tk()
root.geometry('600x400')
#two containers like this.
#trying to hide container_2 untill the user press settingBtn
container_1 = tk.Frame(root, borderwidth=2, relief="solid")
container_2 = tk.Frame(root, borderwidth=2, relief="solid")
startBtn = tk.Button(container_1, text = "Start", command =startFn)
startBtn.grid(row=4, column=4)
stopBtn = tk.Button(container_1, text = "Stop", command= stopFn)
stopBtn.grid(row=5, column=4)
settingBtn = tk.Button(container_1, text = "Settings", command= FnToShow)
settingBtn.grid(row=6, column=4)
setting_1 = tk.Label(container_2, text = "Setting-1", fg='#000000')
setting_1.grid(row=3, column=10)
setting_2 = tk.Label(container_2, text = "Setting-2", fg='#000000')
setting_2.grid(row=4, column=10)
closeSettingBtn = tk.Button(container_2, text = "close Settings", command= FnToHide)
closeSettingBtn.grid(row=5, column=10)
container_1.pack(side="left", expand=True, fill="x", padx=1, pady=1)
container_2.pack(side="right",expand=True, fill="x", padx=1, pady=1)
root.mainloop()

You could show/hide the entire container_2 using the functions FnToShow and FnToHide:
something like this:
import tkinter as tk
def startFn():
pass
def stopFn():
pass
def FnToShow():
container_2.pack(side="right",expand=True, fill="x", padx=1, pady=1)
def FnToHide():
container_2.pack_forget()
root = tk.Tk()
root.geometry('600x400')
container_1 = tk.Frame(root, borderwidth=2, relief="solid")
container_2 = tk.Frame(root, borderwidth=2, relief="solid")
startBtn = tk.Button(container_1, text="Start", command =startFn)
startBtn.grid(row=4, column=4)
stopBtn = tk.Button(container_1, text="Stop", command= stopFn)
stopBtn.grid(row=5, column=4)
settingBtn = tk.Button(container_1, text="Settings", command= FnToShow)
settingBtn.grid(row=6, column=4)
setting_1 = tk.Label(container_2, text="Setting-1", fg='#000000')
setting_1.grid(row=3, column=10)
setting_2 = tk.Label(container_2, text="Setting-2", fg='#000000')
setting_2.grid(row=4, column=10)
closeSettingBtn = tk.Button(container_2, text="close Settings", command= FnToHide)
closeSettingBtn.grid(row=5, column=10)
container_1.pack(side="left", expand=True, fill="x", padx=1, pady=1)
root.mainloop()

i am trying to destroy a window through a def funtion to another but i keep getting this error

when ever I click register it come up with this error
AttributeError: 'function' object has no attribute 'destroy'
I don't understand why it doesn't work i've tried every thing.
the aim of my program for now is that when I run the program it starts with a login screen and if I click sign up it will close the window be going to the log_to_reg definition where it says login_screen and open register_screen

The answer to your error:
AttributeError: 'function' object has no attribute 'destroy'
You have a function named login_screen and you are attempting to call destroy() on that function so it throws an error.
This is partly because you named your function and the root window the same thing. The other part is because the root window is only a local variable within the function so functions outside of the login_screen function cannot see the tkinter instance inside.
You could use global to manage stuff like this but all and all that is not the best option. You really want to avoid using Tk() more than once in tkinter and avoid the use of global.
Instead we can set up each item as a class and use tkinters Toplevel() to open the register window.
Here is a modified version of your code using grid() to manage everything in the window. We can also use withdrow() and deiconify() to manage what windows are visible.
import tkinter as tk

def __init__(self):
tk.Tk.__init__(self)
self.geometry("400x250")
self.title("Tree Road School server")
self.resizable(False,False)

self.columnconfigure(0, weight=1)
self.columnconfigure(2, weight=1)
self.rowconfigure(0, weight=1)
self.rowconfigure(2, weight=1)
center_frame = tk.Frame(self)
center_frame.grid(row=1, column=1, sticky="nsew")
tk.Label(center_frame, text="LOGIN", width = '6', font=('Arial', 25)).grid(row=0, column=0, columnspan=2, padx=10, pady=5)
tk.Label(center_frame, text="username: ", font=(15)).grid(row=1, column=0, padx=10, pady=5)

TKinter update scrolledText

On create window, tkinter.scrolledtext look up for SearchIP() to insert but never update layout. When I have different input for SearchIP() method never show up. It only shows the initial value.
Note: I added a couple of print statements to watch if SearchIP() returns the right thing, which is the case, for example for 'www.google.com' it prints '216.58.192.4', but this value never shows up in ScrolledText.
import socket

frame = tk.Frame(root,width=100)
label = Label(root,text="http://")
label.grid(row=0,column=0)
entryVar = tk.StringVar()

entry.grid(row='0',column='1',columnspan=8)
def SearchIP():

I also tried to modify the SearchIP() method and remove the return statement, but then I got this error:

You have to use insert() inside SearchIP()

This is just a child window that will popup when you click on the menu, I don't get any errors, but Text and Tex1 is not visible on the child window, but when I run this code on its own root window it works just find, maybe the ident is messed up or something? Any help will be appreciated, Thanks.

You don't provide a parent for text or text1. When you call Text() you need to give it an argument like Text(win1) or Text(frame) so that Tkinter knows what to pack the Text widget on.
