Python通过多帧静态图像制作GIF动态图像

import os
import os.path
from PIL import Image
import images2gif
def pngs2gif(gifName, path, duration=0.1, np=0.1):    
    pngFiles = [f for f in os.listdir(path)]
    pngFiles.sort(key=lambda f: int(f[:-4]))
    pngFiles = [os.path.join(path, f) for f in pngFiles]
    images = []
 for f in pngFiles:
        images.append(Image.open(f))
    images2gif.writeGif(gifName, images, duration, np)
pngs2gif('abc.gif', 'test')
