My quiz code is only showing the use of one csv file: using tkinter and python

Question

My quiz is currently only recognizing one of the three csv files sent with it. this is the hardquestion.csv file. I am attempting to have different levels of difficulty Here is my code:

import os
from tkinter import *
import tkinter.messagebox 
import random
#from PIL import ImageTk,Image
global score
score = 0
global count
global filename
count = 0
root = Tk()
root.title('Quiz')
root.config(bg = 'white')
root.geometry('770x555')

def menubutton():
    Easybutton = Button(root, text = 'easy', command = easy())
    Easybutton.pack()

    Mediumbutton = Button(root, text = 'medium', command = medium())
    Mediumbutton.pack()

    Hardbutton = Button(root, text = 'hard', command = hard())
    Hardbutton.pack()

# please read / the filename is always equal to hardquestion.csv / idk why??????

def easy ():
    global filename
    filename = "easyquestion.csv"

def medium():
    global filename
    filename = "mediumquestion.csv"

def hard():
    global filename
    filename = "hardquestion.csv"



class Question:
    def __init__(self, question, correct_ans):
        self.question = question
        self.correct_ans = correct_ans


def ask_quit():
    if tkinter.messagebox.askokcancel("Quit", "The quiz has finished now, would you like to quit?"):
        root.destroy()

def checkResult(letter):
    global score
    if letter == currentQuestion.correct_ans:
        score += 1
    if not len(questions) == 0:
        getNewQuestion()
    else:
        result()
        ask_quit()

def getNewQuestion():
    global count
    global currentQuestion
    currentQuestion = questions.pop()
    for i, var in enumerate((titleVar, aVar, bVar, cVar, dVar)):
        var.set(currentQuestion.question[i])
    count+= 1

def result():
    global score
    s = "your score is " + str(score)
    tkinter.messagebox.showinfo("Result", s)

def buttons():
    question = Label(root, textvariable=titleVar)
    question.pack()

    A = Button(root, textvariable = aVar, command = lambda: checkResult('A'))
    A.pack()

    B = Button(root, textvariable = bVar, command = lambda: checkResult('B'))
    B.pack()

    C = Button(root, textvariable = cVar, command = lambda: checkResult('C'))
    C.pack()

    D = Button(root, textvariable = dVar, command = lambda: checkResult('D'))
    D.pack()

menubutton()
file_handle = os.path.join(os.path.dirname(__file__), filename) 
print(filename)
count = 0
score = 0

questions = []

with open(filename, 'r') as file_handle:
    displayQ = []
    for line in file_handle:
        line_sections = line.strip().split(",")
        displayQ = line_sections[:-1]
        correct_ans = line_sections[-1]
        questions.append(Question(displayQ, correct_ans))

titleVar = StringVar()
aVar = StringVar()
bVar = StringVar()
cVar = StringVar()
dVar = StringVar()

currentQuestion = None
getNewQuestion()

canvas = Canvas(width = 100, height = 100, bg = 'black')
canvas.pack(expand = YES, fill = BOTH)

buttons()

root.mainloop()

You will need 3 .csv files called "easyquestion.csv", "mediumquestion.csv" and 'hardquestion.csv" stored in the same folder. They will look something like this

#easyquestion.csv
what is the smallest country in the world?,a) Monaco,b) Vatican City,c)Luxembourg,d)Maldives,B
what is the largest country in the world?,a)Russia,b)USA,c)India,d)China,A
what is the largest continent in the world?,a)Europe,b)Africa,c)Asia,d)Australia,C

#mediumquestion.csv
where is Genghis Khan from?,a)China,b)Nigeria,c)Mongolia,d)Kazakhstan,C
what is Newton's second law of motion?,a) F=ma,b)E=mc^2,c)mv-mu,d) v=u+at,A
who was the first man to walk on the moon?,a)Buzz Aldrin,b)Neil Armstrong,c)Charles Duke,d)David Scott,B

#hardquestion.csv
In Music what term is used to denote a gradual increase in loudness in a piece of music?,a)cresecendo,b)pitch rise,c)note amplification,d)crese rise,A
How many freds are there in a guitar?,a)29,b)25,c)20,d)22,B
What do the initials POTUS stand for?,a)politicians of the United States,b)prime minister of the United States,c)Parliament of the United States,d)president of the United States,D

Thanks in advance!

Does this answer your question? [Why is Button parameter “command” executed when declared?](https://stackoverflow.com/questions/5767228/why-is-button-parameter-command-executed-when-declared) — fhdrsdg, Feb 06 '20 at 14:38
I tried adding lambda but then it just says that : Traceback (most recent call last): File "/Users/arjyo/Documents/quiz experiments/Actual quiz trial.py", line 102, in file_handle = os.path.join(os.path.dirname(__file__), filename) NameError: name 'filename' is not defined — Arjyo, Feb 06 '20 at 14:51
That makes sense, since you call that line before any button has been pressed so `filename` is indeed not defined. You need to understand event-driven programming to use tkinter. To quote [Bryan Oakley](https://stackoverflow.com/a/9343402/3714930): "Event-driven programming requires a different mindset from procedural code. Your application is running in an infinite loop, pulling events off of a queue and processing them." — fhdrsdg, Feb 06 '20 at 14:59
I tried defining filename by calling the easy, medium and hard functions and it defines the filename. but in doing so the code still only reads the hardquestion.csv file. What am I doing wrong — Arjyo, Feb 07 '20 at 01:48
If you called `easy()`, `medium()` and `hard()` in one go, the result `filename` is obviously `hardquestion.csv`. You need to find a way to let user select difficulty and call the corresponding function to set the `filename`. — acw1668, Feb 07 '20 at 04:31
