Create video from images python

for file in os.listdir('.'): 
    im = Image.open(os.path.join(path, file)) 
    width, height = im.size 
    mean_width += width 
    mean_height += height 
    
  
mean_width = int(mean_width / num_of_images) 
mean_height = int(mean_height / num_of_images) 
  
  
for file in os.listdir('.'): 
    if file.endswith(".jpg") or file.endswith(".jpeg") or file.endswith("png"): 
        
        im = Image.open(os.path.join(path, file))

        print(width, height) 
  
        
        imResize = im.resize((mean_width, mean_height), Image.ANTIALIAS)  
        imResize.save( file, 'JPEG', quality = 95) 
        
        print(im.filename.split('\')[-1], " is resized")
