Tkinter unable to clear the label

Question

import tkinter
import random
import time


score = 0
num1 = random.randint(1, 10)
num2 = random.randint(1, 10)
result = num1 + num2
timeleft = 30

def add():
    return num1 + num2

def mul():
    return num1 * num2

def div():
    return num1 // num2

def sub():
    return num1 - num2

operation = {'-' : sub, '/' : div, '*' : mul, '+' : add}
op = random.choice(list(operation.keys()))

def calculate(op):
    return operation[op]()

def start(event):
    if timeleft == 30:
        countdown()  
    question()

def question():
    global score
    global timeleft
    
    if timeleft > 0:
        global num1, num2, result, operation
        
        
        e.focus_set()
        
        result = 0
        for i in e.get():
            if (i.isdigit()):
                result = result *10 + int(i)
        if (e.get()[0] == '-'):
            result *= -1

        actualResult = calculate(op)
        if result == actualResult:  
            score += 1
        else:
            score -= 1  
        label.config(text = "")
        label.config(fg = "red",text = str(num1)+ ' ' + op +" "+str(num2), font = ('Helvetica', 60))
        time.sleep(2)
        e.delete(0, tkinter.END)
        num1 = random.randint(1, 10)
        num2 = random.randint(1, 10)

        label.config(fg = "Black",text = str(num1)+ ' ' + op +" "+str(num2), font = ('Helvetica', 60))
        scoreLabel.config(text = "Score: " + str(score))


def countdown():

    global timeleft
    if timeleft > 0:

        timeleft -= 1
        timeLabel.config(text = "Time left: " + str(timeleft))
    
        timeLabel.after(1000, countdown)



root = tkinter.Tk()

root.maxsize = (400, 400)
root.minsize = (400, 400)



canvas = tkinter.Canvas(root, width=400, height=400,  highlightthickness = 0)
canvas.pack()
imgDir = r"C:\Users\monster pc\Downloads\mathImg.png"


background_image = tkinter.PhotoImage(file=imgDir)
canvas.create_image(0, 0, anchor=tkinter.NW, image=background_image)

instruction = tkinter.Label(root, text = "Type the solution and press enter",font = ('Helvetica', 15), highlightthickness=0, highlightbackground=None)

scoreLabel = tkinter.Label(root, text = "Press enter to start",font = ('Helvetica', 20), highlightthickness=0, highlightbackground=None)
scoreLabel.pack()


timeLabel = tkinter.Label(root, text = "Time left: " + str(timeleft), font = ('Helvetica', 12))
timeLabel.pack()



num1 = random.randint(1, 10)
num2 = random.randint(1, 10)
label = tkinter.Label(root, font = ('Helvetica', 60))
label.config(text = str(num1)+ ' '+op + " "+str(num2))
label.pack()


e = tkinter.Entry(root)

e.pack()


e.focus_set()
canvas.create_window(200,50, window =instruction)
canvas.create_window(200, 80, window =scoreLabel)
canvas.create_window(200, 120, window = timeLabel)
canvas.create_window(200, 200, window = label)
canvas.create_window(200, 250, window = e)


while root.bind('<Return>', start):
    root.update()

I'm unable to clear the label widget i want to update the label when user types the answer just show the answer and the update the lable again for the the next quesion (next two random number)

I've tried: *sleep(1) func *after(1000) function nothing is working i've even tried clearing the label widget as label.config(text = "")

Tkinter unable to clear the label

Your code is working.

• Comment out line 57 #label.config(text = ""). So you don't need it.
• Set it to 250 canvas.create_window(200, 250, window = e)
