📸 Basic Screenshot Tool in Python (CMD Version)

If you're just starting, the simplest way to take a screenshot in Python is by using the pyautogui library.

Step 1: Install pyautogui

Open your terminal and install the library:

pip install pyautogui

Step 2: Write the Script

Here's the minimal Python script to capture the entire screen:

import pyautogui

screenshot = pyautogui.screenshot()
screenshot.save("screenshot.png")

✅ That's it! Run this script, and it will automatically capture your current screen and save it as screenshot.png in your working directory.

🖥️ Building a Full GUI Screenshot Tool in Python

Now, let’s step it up and create a graphical screenshot application using Tkinter, Pillow, and ImageGrab.
This tool will allow users to:

• Capture the full screen
• Select a specific area
• Edit the screenshot (draw annotations)
• Save the final result

Step 1: Install Required Libraries

Make sure you have the necessary libraries:

pip install pillow

(Tkinter usually comes pre-installed with Python.)

📂 How to Add an App Icon

To make the window even more polished, you can add a custom icon.ico:

• Download free icons from IconArchive or Favicon.io.
• Place the icon.ico in the same folder as your script.
• The line self.root.iconbitmap('icon.ico') sets the window icon.
