我不能用来自枕头的close()来关闭列表中的图像

Question

我用Image.open()打开图像，并将它们存储在2d列表“映像”中。但是现在我尝试使用close()函数关闭所有图像，代码编译，但是它没有关闭文件

for i in range(len(images)):
    for j in range(len(images[i])):         
        print(images[i][j])
        images[i][j].close()

print(images)

output:
<PIL.Image.Image image mode=RGBA size=1080x1080 at 0x7F9BD4A6A280>
<PIL.PngImagePlugin.PngImageFile image mode=RGBA size=1080x1080 at 0x7F9BD4A6A3D0>

关闭图像会使其从前一点开始无法使用，但不会从列表中删除。如果你试图对这些图像做任何事情，你几乎肯定会有一个错误。也许在你关闭它之后，你应该用None代替它

images[i][j] = None
