帮我写一个python脚本，用于对比两张图片的差异

好的，以下是用Python对比两张图片差异的脚本代码：

from PIL import Image

def compare_images(image1_path, image2_path):
    img1 = Image.open(image1_path)
    img2 = Image.open(image2_path)

    if img1.size != img2.size:
        print("The images have different sizes.")
        return False

    pairs = zip(img1.getdata(), img2.getdata())
    if len(img1.getbands()) == 1:
        dif = sum(abs(p1 - p2) for p1, p2 in pairs)
    else:
        dif = sum(abs(c1 - c2) for p1, p2 in pairs for c1, c2 in zip(p1, p2))

    n_components = img1.size[0] * img1.size[1] * 3
    difference = (dif / 255.0 * 100) / n_components
    print("The images are {:.2%} different.".format(difference))
    return True

if __name__=="__main__":
    image1_path = "image1.jpg"
    image2_path = "image2.jpg"
    compare_images(image1_path, image2_path)

你可以将 `image1_path` 和 `image2_path` 换成你自己要比较的图片路径。这个脚本会输出两张图片的差异度百分比。越接近0，说明两张图片越相似。
