🕒 Digital Clock with Theme Switcher (Python Tkinter Project)

📌 Project Overview

This is a simple yet functional digital clock application built using Python’s Tkinter GUI toolkit. It displays the current time in 12-hour format (with AM/PM) and allows users to switch between light and dark themes dynamically using a menu bar.

The clock updates every second, ensuring accurate real-time display.

🚀 Features

• ✅ Displays time in HH:MM:SS AM/PM format
• ✅ Live update every second (using Tkinter’s after method)
• ✅ Light and Dark theme options accessible via menu
• ✅ Clean, minimalistic UI
• ✅ Resizable window

💡 How it Works

• The app creates a main window using Tkinter.

• A menu bar allows users to choose between:

• Light theme → white background with black text

• Dark theme → dark blue background with black text

• When a theme is selected, a new frame is created and placed on the window, with a clock label inside it.

• A nested time() function fetches the current time using strftime() and updates the clock label every second using after(1000, time).

• The app starts with a default theme (light blue frame with clock).

🖥️ Code Highlights

def light_theme():
    # Creates a white frame with a black clock
    # Updates time every second using after()

def dark_theme():
    # Creates a dark blue frame with black clock text

def time():
    # Fetches time as string and updates label
    # Calls itself after 1000 ms (1 second)

theme_menu.add_command(label="Light", command=light_theme)
theme_menu.add_command(label="Dark", command=dark_theme)

👉 The theme switching is done via a menu bar dropdown, not buttons.

⚡ Technologies Used

• Python 3

• Tkinter (built-in GUI library)

• time module (strftime for time formatting)

💻 How to Run

1. Clone the repository

git clone https://github.com/Mazid2003/Digital-Clock-using-python-Tkinter.git

cd Digital_clock

1️⃣ Make sure you have Python 3 installed.

2️⃣ Run the script:

python digital_clock.py

✅ The app window will open, showing the clock and theme menu.

✨ Possible Enhancements

• If you plan to showcase future ideas on GitHub, you can list:

• Destroy previous theme frames (so they don’t overlap on repeated switches)

• Add more themes (neon, green terminal, etc.)

• Add date display

• Show timezone

• Full-screen clock mode

📝 Summary for GitHub

• This is a beginner-friendly Python GUI project showcasing:

• Tkinter layout management

• Real-time clock updates

• Dynamic theme switching

It can serve as a base for more advanced clock apps!
