Example of drawing and loading image animation effects implemented by Python3,

This article describes how to draw and attach animated images in Python3. We will share this with you for your reference. The details are as follows:

#__ * _ Coding: UTF-8 _ * __# python3import timefrom tkinter import * def moveImage (event): if event is the function to be bound to the move of the logo.gif image. keysym = 'up': canvas. move (,-3) # move the object whose ID is 1, so that the X-axis is 0, and the X-axis is 3 elif event. keysym = 'low': canvas. move (1, 0, + 3) elif event. keysym = 'left': canvas. move (1,-3, 0) elif event. keysym = 'right': canvas. move (1, 3, 0) tk. update () time. sleep (0.05) def changeColor (event): if event. keysym = 'up': canvas. itemconfig (pg, fill = 'blue') # fill in things whose ID is pg and fill in bluetk = Tk () # window canvas = Canvas (tk, width = 400, height = 400) # canvas. pack () # myImage = PhotoImage (file = 'C: \ Users \ lai \ Desktop \ logo.gif ') # The image format must be gif im = canvas. create_image (0, 0, anchor = NW, image = myImage) # Load image pg = canvas. create_polygon (10, 10, 10, 60, 50, 35, fill = 'red') # create a triangle print (im); print (pg) # display the image and triangle IDcanvas. bind_all ('<KeyPress-Up>', moveImage) # bind the direction key upcanvas. bind_all ('<KeyPress-Down>', moveImage) canvas. bind_all ('<KeyPress-Left>', moveImage) canvas. bind_all ('<KeyPress-Right>', moveImage) # canvas. bind_all ('<KeyPress-Up>', changeColor)

Running result:

You can move an image after pressing the Left or Right key.
