您只需使用全局变量。 1)删除lambda,然后输入函数名称 2)此外,您可以添加其他if / else arg。
image_list = [img1, img2, img3, img4, img4, img5, img6, img7, img8, img9, img10,
img11, img12, img13]
img_index = 0
def forword():
global img_index
img_index += 1 # THis will help to move img_index by 1
label = Label(root, image=image_list[img_index]) # with 'image_list[img_index]' you will get img. name on that index
label.grid()
def backward():
global img_index
img_index -= 1
label = Label(root, image=image_list[img_index])
label.grid()
