Hello,

pyscript is crashing if count = 0 declare inside def check(guess):
otherwise i get local variable 'count' referenced before assignment

import tkinter
from random import randint
from tkinter import messagebox


low = 0
high = 10
rand = randint(low,high)
print(rand)
essai = 10
count = 0
def check(guess):
    while(guess!=rand):
        if guess < rand:
            txtMess.configure(text = 'Trop bas')

        elif guess > rand:
            txtMess1.configure(text = 'Trop haut')

        else:
            txtMess2.configure(text = f"Bravo! {guess} est le bon nombre")
        count = count + 1


    print('count',count)

tk = tkinter.Tk()
tk.title('Deviner le nombre')

label = tkinter.Label(tk, text = f"Devinez un nombre entre {low} et {high} inclusivement")
label.pack()

entry =  tkinter.Entry(tk)
entry.pack()

button = tkinter.Button(tk, text = 'Devine', command = lambda: check(int(entry.get())) )
button.pack()

txtMess = tkinter.Label(tk, text = "")
txtMess.pack()

txtMess1 = tkinter.Label(tk, text = "")
txtMess1.pack()

txtMess2 = tkinter.Label(tk, text = "")
txtMess2.pack()

tk.mainloop()

Any explaination for that?
BTW anyone know a good compiler easy to use and light to install?

Thank you

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()

Your code reset the random number every tries.
So its impossible to find the number. If you type 5 its to high if you type 4 its too low
The while loop is to calculate the number of tries.

But thank you for this part of the code: check.count = getattr(check, 'count', 0)
count = check.count + 1
check.count += 1

I just tried it and its working fine.

Change

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

to this

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

The number should remain the same. The script will have to be restarted to get a new number

Yes its cool thank you!

Updated code to clear entry field on button submit, rest count, and get new number on correct guess of number

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', rnd.randint(0, 10))
    # random_number = rnd.randint(0, 10)
    return randnum.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 = 0
        randnum.number = rnd.randint(0, 10)

    check.count += 1
    entry.delete(0, tk.END)


root = tk.Tk()
root['padx'] = 8
root['pady'] = 5

guess_label = tk.Label(root, text='Tries:')
guess_label.pack()
label = tk.Label(root, text='Type a number between 0 and 10')
label.pack()
entry = tk.Entry(root)
entry.pack()
btn = tk.Button(root, text='Submit')
btn['command'] = lambda: check(entry.get())
btn.pack()
entry.focus()

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

root.mainloop()

I was not asking that much but thank you again.

Sorry, I intend to go overboard sometimes.
