pip install Pillow -i https://mirrors.aliyun.com/pypi/simple pip install moviepy -i https://mirrors.aliyun.com/pypi/simple
默认官方镜像源，我这里尝试的时候没有任何进度。切换到国内的源，比如阿里镜像，清华镜像即可。第一次使用国内源，简直是神速！

图片
from PIL import Image, ImageOps
img = Image.open('img/python.jpg')
img_mirror = ImageOps.mirror(img)
img_mirror.save('img/python_mirror.jpg')
视频
import moviepy
from moviepy.editor import VideoFileClip,vfx
video = VideoFileClip('video/video.mp4')
reversed_video = video.fx(vfx.mirror_x)
reversed_video.write_videofile('video/vide_reverse.mp4')
