Python：关闭使用scipy.misc.imread打开的文件

Question

In Python one can read in an image with scipy like so:

from scipy.misc import imread

img = imread('cats.jpg')

How can one close that opened file?

Answer 1

Okay, Scipy uses PIL under the cover, and PIL supports a with block syntax that automatically closes the file when the block is exited:

from PIL import Image

with Image.open('test.png') as test_image:
    do_things(test_image)
