Tkinter: radio button getting dataset and a function to find matches and mismatches between datasets

Quite new in Python. I am trying to create an interface with different radiobuttons. Each radiobutton gets a dataset. Two buttons that when are clicked recall two different functions: find matches and mismatches between the datasets selected by the radiobuttons. the result is printed in a widget. I really cannot get to work the functions of matching and mismatching. Can I have help to know how to proceed please? Best,

**from tkinter import *
from tkinter import messagebox
root = Tk()
root.geometry('400x400')
root.title("matches and mismatches")
def matches():
    messagebox.showinfo("function of finding matches")
def mismatches():
    messagebox.showinfo("function of finding mismatches")
Datasetone = ["Michel", "John", "Carol", "Bob", "Justine", 'Harry',]
Datasettwo = ["Justine", "John", "Carol", "Bob", "Josh", "Marcello"]
Radiobutton(root, text='Dataset one').pack()
Radiobutton(root, text='Dataset two').pack()
Matches = Button(root, text='Matches', command=matches).pack()
Mismatches = Button(root, text='Mismatches', command=mismatches).pack()
root.mainloop()**

here is example code of how it can be done. It is simple so you can understand it better.

import tkinter as tk
from tkinter import messagebox

root = tk.Tk()
root.geometry('400x400')
root.title("matches and mismatches")

var = tk.IntVar()
var2 = tk.IntVar()


data_set_one = ["Michel", "John", "Carol", "Bob", "Justine", "Harry"]
data_set_two = ["Justine", "John", "Carol", "Bob", "Josh", "Marcello"]

dictionary = [{"id": 1, "data_set": data_set_one}, {"id": 2, "data_set": data_set_two}]


def matches(set1, set2):
    for item in dictionary:
        if item["id"] == set1.get():
            first_set = item["data_set"]
        elif item["id"] == set2.get():
            second_set = item["data_set"]
        else:
            continue
    match = []
    for k in first_set:
        for v in second_set:
            if k == v:
                match.append(k + ',')
    messagebox.showinfo("Matches", message=match)


def mismatches(set1, set2):
    for item in dictionary:
        if item["id"] == set1.get():
            first_set = item["data_set"]
        elif item["id"] == set2.get():
            second_set = item["data_set"]
        else:
            continue
    mismatch = []
    for k in first_set:
        if k not in second_set:
            mismatch.append(k + ',')
    messagebox.showinfo("Mismatches", message=mismatch)


tk.Radiobutton(root, text='Dataset one', variable=var, value=1).pack()
tk.Radiobutton(root, text='Dataset two', variable=var2, value=2).pack()
Matches = tk.Button(root, text='Matches', command=lambda: matches(var, var2)).pack(pady=5)
Mismatches = tk.Button(root, text='Mismatches', command=lambda: mismatches(var, var2)).pack(pady=5)
root.mainloop()

Import is changed from from tkinter import * to import tkinter as tk. Two variables var and var2 are created and they are int type. After list of dictionary is created where every data_set is given its id. In radiobuttons, variable and value is added. (for every dataset there is tk.IntVar() and value is equal to id inside dictionary). Two functions, mismatches and matches are created and both functions have two parameters. Inside function matches we check if id inside dictionary is equal to selected radiobutton, and if it is, variable first_set is assigned value of dictionary for that item. Empty list match is created and inside two loops we check if two list have matching items, and if there is matching item, it is added to list match. In messagebox title is set and message is equal to match. In mismatches function everything is similar to matches function. In mismatches 2nd way of getting matches/mismatches is displayed in for loop.
