Build Your Own Login App with PySimpleGUI: Checking Username and Password! 🚀✨

Hello, CodeCrafters! 👋 

Ready to build something cool and useful?

Today, we’re diving into creating a simple login app using PySimpleGUI!

We'll learn how to check a username and password. This project is fun, easy, and a fantastic way to level up your coding skills!

Let's get started! 🎉

Step 1: Install PySimpleGUI

First things first, if you haven’t installed PySimpleGUI yet, open your terminal or command prompt and type:

pip install pysimplegui

Now that you have PySimpleGUI installed, we’re all set to start coding!

Step 2: Import the Library

We'll start by importing PySimpleGUI:

import PySimpleGUI as sg

Step 3: Design the Layout

Let's design our login window. We need fields for the username and password, and a button to submit the login details.

layout = [

    [sg.Text('Username'), sg.InputText(key='-USERNAME-')],

    [sg.Text('Password'), sg.InputText(key='-PASSWORD-', password_char='*')],

    [sg.Button('Login'), sg.Button('Cancel')]

]

Step 4: Create the Window

Next, we create a window with the specified layout:

window = sg.Window('Login App', layout)

Step 5: Event Loop (The Fun Part!)

Here's where the magic happens! We’ll create an event loop that checks for button clicks and retrieves the input values.

while True:

    event, values = window.read()

    if event sg.WIN_CLOSED or event 'Cancel':

        break

    username = values['-USERNAME-']

    password = values['-PASSWORD-']

    if username 'admin' and password 'secret':

        sg.popup('Login Successful!')

    else:

        sg.popup('Login Failed. Try Again.')

window.close()

Step 6: Putting It All Together

Here’s the complete code:

import PySimpleGUI as sg

layout = [

    [sg.Text('Username'), sg.InputText(key='-USERNAME-')],

    [sg.Text('Password'), sg.InputText(key='-PASSWORD-', password_char='*')],

    [sg.Button('Login'), sg.Button('Cancel')]

]

window = sg.Window('Login App', layout)

while True:

    event, values = window.read()

    if event sg.WIN_CLOSED or event 'Cancel':

        break

    username = values['-USERNAME-']

    password = values['-PASSWORD-']

    if username 'admin' and password 'secret':

        sg.popup('Login Successful! 🎉')

    else:

        sg.popup('Login Failed. Try Again. 😞')

window.close()

Step-by-Step Breakdown:

1. Designing the Layout:

• We create text labels and input fields for the username and password. The password_char='*' ensures that the password is hidden when typed.

2. Creating the Window:

• We initialize the window with the layout we designed.

3. Event Loop:

• The loop reads events (like button clicks) and values (input text).

• If the window is closed or 'Cancel' is clicked, the loop breaks, and the window closes.

• It checks if the username is 'admin' and the password is 'secret'. If they match, a success message pops up. If not, an error message is displayed.

Output

Why This Is Fun and Useful:

• Real-World Application: Creating a login system is a fundamental skill in app development.

• Interactive Learning: You get to see immediate results of your code, making learning more engaging.

• Customizable: You can easily extend this app to check against a database or file, add more features, and make it your own!
