Unable to count the number of tries in guessing game.

[menator01]

I do not understand the while loop inside the check function.
Crashing probably because the count is not global inside the function.
Anyway I done a version of your game.

import tkinter as tk
from tkinter import messagebox as mb
import random as rnd


def randnum():
    '''
        Function for getting and returning a random number.
        Default value is 0
    '''
    randnum.number = getattr(randnum, 'number', 0)
    random_number = rnd.randint(0, 10)
    return random_number

def check(guess):
    '''
        Function for checking guessed number against random number.
        Increases count for guessing. Sets count default 0
        Updates labels accordingly
    '''
    check.count = getattr(check, 'count', 0)
    count = check.count + 1
    guess_label['text'] = f'Tries: {count}'

    random_number = randnum()

    if int(guess) > random_number:
        msg['text'] = 'Too High'
    elif int(guess) < random_number:
        msg['text'] = 'Too Low'
    else:
        msg['text'] = f'Great! You guessed {random_number}'

    check.count += 1
    

root = tk.Tk()
root['padx'] = 8
root['pady'] = 5
num = tk.IntVar()
guess_label = tk.Label(root, text='Tries:')
guess_label.pack()
label = tk.Label(root, text='Type a number')
label.pack()
entry = tk.Entry(root, textvariable=num)
entry.pack()
btn = tk.Button(root, text='Submit')
btn['command'] = lambda: check(entry.get())
btn.pack()

msg = tk.Label(root)
msg.pack()

root.mainloop()
