Hi there, beginner to programming here.
I'm currently working on an assessment which requires me to code a simple login system using python. I've managed to do most of it myself and works well, but one feature I need and can't figure out is a password generator button in the menu. I've already got the button on the menu of my GUI, and once clicked it opens a window where I need to code the password generator into. The password generator needs to allow the user to choose how many characters they want, and whether they want/don't want to use normal characters, integers and/or special characters. Any help would be so appreciated. Here is my code so far:
from tkinter import *
import os
import random
# Creating the main menu window.
def main_menu():
# Making the main_window variable global so it can be used more widely.
global main_window
main_window = Tk()
# Defining the dimensions and title of the main menu window.
main_window.geometry("400x400")
main_window.title("Login System")
# Label that displays "Select an option" on the main menu.
LabelNum1 = Label(main_window,text="Select an option" , bg="white" , fg="red")
LabelNum1.pack(fill=X, pady=20)
# This is the properties for the first Login button.
loginButtonMain = Button(main_window,text="Login",width="30", height="2",command=login)
loginButtonMain.pack(pady=20)
# This is the properties for the first register button.
