Both Checkboxes Checked when one clicked

I am making an app for a project called the organizer. It is an organization app. I have an issue that when you check one check box, they all check off.

How do I fix this?

After ran go to: Checklist -> Enter A Value -> Click "Add Assignment" -> Repeat A few times -> try to click one

Also, my .update() works, but still seems to cause an error? Do you know why?

Thanks!

import tkinter as tk
root = tk


AsgnList = []
#Initialization
class TheOrganizer(tk.Tk):

    def __init__(self, *args, **kwargs):

        tk.Tk.__init__(self, *args, **kwargs)


        container = tk.Frame(self)         
        self.geometry('500x500')        
        container.pack(side="top", fill="both", expand = True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}

        for F in (StartPage, AddAsgnPage):        

            frame = F(container, self)    
            self.frames[F] = frame    
            frame.grid(row=0, column=0, sticky="nsew")

You are using the same variable for both checkboxes. Move the variable creation to inside the loop, to use different variables.

var_list = []
for z in AsgnList:
    var = tk.IntVar()
    tk.Checkbutton(self, text=z, variable=var).place(x=200,y=yVal)
    yVal += 25         
    var_list.append(var)

That said, you probably want to store the variables so you can check which checkboxes are marked later. So I added a var_list list object to store all created vars.
