Building a Simple Login Interface with Python

In this guide, we'll walk you through building a simple login interface using Python. We'll use Tkinter for the graphical interface and SQLite for the database to store user credentials.

Step 1: Setting Up the Environment

First, ensure you have Python installed. You can download it from the official Python website. We will use the tkinter library for the GUI and sqlite3 for the database. Both libraries come pre-installed with Python.

Step 2: Creating the Database

We'll create an SQLite database to store user credentials.

1. Create a new Python file, create_db.py:

    import sqlite3
   
    conn = sqlite3.connect('users.db')
    c = conn.cursor()
   
    c.execute('''
              CREATE TABLE IF NOT EXISTS users
              (id INTEGER PRIMARY KEY,
              username TEXT NOT NULL,
              password TEXT NOT NULL)
              ''')
   
    conn.commit()
    conn.close()
   

2. Run this script to create users.db with a table named users.

Step 3: Building the Login Interface

Next, we'll create the GUI for the login interface using Tkinter and iptv españa.

1. Create a new Python file, login.py:

    import tkinter as tk
    from tkinter import messagebox
    import sqlite3
   
    # Function to handle user login
    def login():
        username = entry_username.get()
        password = entry_password.get()
   
        conn = sqlite3.connect('users.db')
        c = conn.cursor()
   
        c.execute('SELECT * FROM users WHERE username=? AND password=?', (username, password))
        result = c.fetchone()
   
        if result:
            messagebox.showinfo('Login Status', 'Login Successful')
        else:
            messagebox.showerror('Login Status', 'Invalid username or password')
   
        conn.close()
   
    # Function to handle user registration
    def register():
        username = entry_username.get()
        password = entry_password.get()
   
        conn = sqlite3.connect('users.db')
        c = conn.cursor()
   
        c.execute('INSERT INTO users (username, password) VALUES (?, ?)', (username, password))
        conn.commit()
        conn.close()
   
        messagebox.showinfo('Registration Status', 'Registration Successful')
   
    # Creating the main window
    root = tk.Tk()
    root.title('Login Interface')
   
    # Creating and placing labels and entry widgets
    tk.Label(root, text='Username').grid(row=0, column=0)
    entry_username = tk.Entry(root)
    entry_username.grid(row=0, column=1)
   
    tk.Label(root, text='Password').grid(row=1, column=0)
    entry_password = tk.Entry(root, show='*')
    entry_password.grid(row=1, column=1)
   
    # Creating and placing buttons
    tk.Button(root, text='Login', command=login).grid(row=2, column=0)
    tk.Button(root, text='Register', command=register).grid(row=2, column=1)
   
    root.mainloop()
   

Step 4: Running the Application

1. Ensure create_db.py has been run to create the users.db file iptv nederland.

2. Run the login.py script:

    python login.py
   

This script will open a window with fields for username and password, along with buttons to login and register iptv abonnement.

Step 5: Testing the Application

1. Register a new user by entering a username and password, then clicking the "Register" button. You should see a success message.

2. Test logging in with the same credentials. If successful, you’ll see a login success message.

Conclusion

You now have a basic login interface with user registration capabilities using Python, Tkinter, and SQLite. This can be expanded and secured further by hashing passwords and adding more features as needed.
