Build Your Own Random Password Generator 🔒🎉

Welcome back, CodeCrafters!

Today, we’re diving into a super fun and practical project: building a random password generator using PySimpleGUI.

Whether you’re securing your online accounts or just love tinkering with Python, this is a great way to flex your coding muscles.

We'll walk through the process step by step, making sure everything is clear and friendly for beginners.

Ready to get started?

Let’s go!

Step 1: Setting Up Your Environment

First, make sure you have PySimpleGUI installed.

If not, open your command prompt or terminal and run:

pip install pysimplegui

This will install the library we’ll use to create our GUI (Graphical User Interface). PySimpleGUI makes it easy to build user-friendly interfaces without getting bogged down in the details.

Step 2: Designing the GUI Layout

Now, let’s start by designing the layout of our password generator.

Imagine what the app will look like: a simple window with a button to generate the password and a field to display it.

Here’s how you can set it up in Python:

import PySimpleGUI as sg

# Define the layout

layout = [

    [sg.Text('Random Password Generator', size=(30, 1), font=("Helvetica", 25))],

    [sg.Text('Your New Password:', size=(20, 1)), sg.InputText('', key='-PASSWORD-', size=(30, 1))],

    [sg.Button('Generate', font=("Helvetica", 12)), sg.Button('Exit', font=("Helvetica", 12))]

]

# Create the window

window = sg.Window('Password Generator', layout)

Explanation:

• We’re using:

  •  sg.Text to display text

  • sg.InputText for the password field, and

  • sg.Button for the buttons.

• The layout variable defines how our window will be structured.

Step 3: Adding the Logic to Generate Passwords

Now comes the exciting part—adding the logic to generate random passwords.

We’ll use Python’s random and string libraries to create a mix of letters, numbers, and symbols.

Here’s the code:

import random

import string

def generate_password(length=12):

    characters = string.ascii_letters + string.digits + string.punctuation

    password = ''.join(random.choice(characters) for i in range(length))

    return password

Explanation:

• The generate_password function creates a password by randomly choosing characters from a pool of letters, numbers, and symbols.

• We’ve set the default length to 12 characters, but you can easily adjust this.

Step 4: Linking the Logic with the GUI

Now, we need to link our password generator with the GUI so that when you click the "Generate" button, it creates a new password.

Here’s how to do it:

while True:

    event, values = window.read()

    if event sg.WINDOW_CLOSED or event 'Exit':

        break

    if event == 'Generate':

        new_password = generate_password()

        window['-PASSWORD-'].update(new_password)

window.close()

Explanation:

• This is where the magic happens!

• We use a loop to keep the window open and check for user interactions.

• When the "Generate" button is clicked, we call generate_password() and update the text field with the new password.

Step 5: Running Your App

That’s it!

Run your Python script, and you’ll see your shiny new password generator in action.

Click "Generate," and watch as it instantly creates a secure, random password.

# Full code example

import PySimpleGUI as sg

import random

import string

def generate_password(length=12):

    characters = string.ascii_letters + string.digits + string.punctuation

    password = ''.join(random.choice(characters) for i in range(length))

    return password

layout = [

    [sg.Text('Random Password Generator', size=(30, 1), font=("Helvetica", 25))],

    [sg.Text('Your New Password:', size=(20, 1)), sg.InputText('', key='-PASSWORD-', size=(30, 1))],

    [sg.Button('Generate', font=("Helvetica", 12)), sg.Button('Exit', font=("Helvetica", 12))]

]

window = sg.Window('Password Generator', layout)

while True:

    event, values = window.read()

    if event sg.WINDOW_CLOSED or event 'Exit':

        break

    if event == 'Generate':

        new_password = generate_password()

        window['-PASSWORD-'].update(new_password)

window.close()

Wrapping Up

You’ve just built a random password generator with PySimpleGUI! 🎉

Not only is this project useful, but it’s also a great way to get comfortable with Python and GUI development.

As you can see, PySimpleGUI makes it super easy to create user-friendly apps.

The Loop-de-Loop:

Writing nested loops can feel like trying to untangle holiday lights. It looks simple at first, but soon you’re deep in a tangle wondering how it got so complicated.
