如何显示图像，关闭并显示下一个图像

Question

我想为美国手语手柄制定培训计划。我为字母组的每个字母都有一个图像库，想一次通过一个字符读取脚本，然后显示一组毫秒数的手指下图像，然后转到下一个图像。 我是编程的新手，很喜欢以菜鸟为导向的答案，谢谢！ 该脚本根据“ Awesome.txt”中的文本打开了正确的图像，但是我有一些我不知道如何解决的问题：

1. 这些图像在Windows照片中打开，另一个在另一个上堆放。我需要它们在屏幕上闪烁以获取毫秒＃的集合，并由下一个图像替换。
2. 如果角色不是字母，我需要一个捕捉，因此它会跳过并继续前进。 这是我到目前为止写的代码：

from PIL import Image
delaytime=input("set speed in milliseconds")
def displayme(imagename):
    image = Image.open(imagename)
    image.show()
    time.sleep(int(delaytime)/1000)
    image.close()
file = open('awesome.txt', 'r')
while 1:
    # read by character
    char = file.read(1)
    imagename=char+".png"
    if not char:
        break
    displayme(imagename)
file.close()

Answer 1

这就是我想到的：

import tkinter
from PIL import ImageTk, Image


def load_images_from(file_path):
    # Returns list of image objects enumerated in file
    images = []
    # with is a whats called context manager which
    # in this case will automatically close opened file
    with open(file_path, "r") as file:
        for line in file.readlines():
            if line:
                images.append(
                    ImageTk.PhotoImage(
                        Image.open(f"{line.strip()}.png"),
                    )
                )
    return images


def main():
    # create new window object
    window = tkinter.Tk()
    # load images and keep index of currently displayed
    # whats interesting, tkinter seems not to properly
    # handle reference counting of images (it doesn't keep
    # them alive?) as without keeping images in array, they
    # doesn't seem to show.
    images = load_images_from("awesome.txt")
    index = 0
    # insert widgets into window frame
    label_component = tkinter.Label(window, image=images[index])
    label_component.pack()

    # clicking in window will result changing image
    def callback(event):
        nonlocal index
        index += 1
        # check index error, if it is pointing behind the array
        # it means we have already shown all of the images so we can exit
        if index >= len(images):
            window.destroy()
            return
        # change currently displayed image
        label_component.configure(image=images[index])

    # attach event listener which will call callback() every
    # time left mouse button is clicked
    window.bind("<1>", callback)
    # keeps script alive as program goes
    window.mainloop()


if __name__ == "__main__":
    main()

尝试 this 用于间隔调用回调函数
