Learn how to work with images in Python using the Pillow library. This exercise will teach you to:

• Open images from a given path
• Get image size and user input for cropping
• Crop an image using coordinates
• Preview the cropped image
• Optionally save the cropped image to disk

• Python 3.x
• Pillow library (pip install pillow)
• Basic understanding of functions, user input, and file paths

1. Get an image path from the user Use input() to ask for the file path.

2. Open the image

   img = Image.open(path)

3. Display image size

   print(img.size)

4. Ask the user for crop coordinates

   • left, top, right, bottom Make sure they are integers and within image dimensions.

5. Crop the image

   cropped_img = img.crop((left, top, right, bottom))

6. Show the cropped image

   cropped_img.show()

7. Optionally save the image

   • Ask the user if they want to save (Y/N)

   • Get folder path and filename from the user

   • Save using:

     cropped_img.save(os.path.join(folder, filename))

8. Handle errors gracefully

   • File not found
   • Invalid input
   • Any unexpected exceptions

Enter photo path: example.jpg
Image size: (1920, 1080)
Crop data: 
Enter left pixel: 100
Enter top pixel: 100
Enter right pixel: 800
Enter bottom pixel: 600
Photo cropped! Details: (100, 100, 800, 600)
Do you want to save this photo? (Y/N): Y
Enter a path (folder) to save: ./cropped
Enter photo name (with extension, e.g., cropped.jpg): my_crop.jpg
Photo saved in ./cropped/my_crop.jpg
