img = qr.make_image(fill_color=color, back_color=bg_color)
img.save(filename)

if not data:
print("Error: Data cannot be empty.")

try:
size = int(input("Enter the size (box size, default is 10): ").strip() or '10')
border = int(input("Enter the border size (default is 4): ").strip() or '4')
except ValueError:
print("Invalid size or border. Using default values.")
size = 10
border = 4

color = input("Enter the QR code color (default is 'black'): ").strip() or 'black'
bg_color = input("Enter the background color (default is 'white'): ").strip() or 'white'

generate_qr_code(data, filename, size, border, color, bg_color)

if __name__ == "__main__":
