Python3實現的畫圖及載入圖片動畫效果樣本，

本文執行個體講述了Python3實現的畫圖及載入圖片動畫效果。分享給大家供大家參考，具體如下：

#__*__coding:utf-8__*__#python3import timefrom tkinter import *def moveImage(event):#圖片logo.gif的移動要綁定的函數  if event.keysym=='Up':    canvas.move(1,0,-3)#移動ID為1的事物，使得橫座標加0，縱座標減3  elif event.keysym=='Down':    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')#填充ID為pg的事物，填充為bluetk=Tk()#視窗canvas=Canvas(tk,width=400,height=400)#畫布canvas.pack()#顯示出來myImage=PhotoImage(file='C:\\Users\\lai\\Desktop\\logo.gif')#圖片格式必須為gif格式im=canvas.create_image(0,0,anchor=NW,image=myImage)#載入圖片pg=canvas.create_polygon(10,10,10,60,50,35,fill='red')#建立三角形print (im);print (pg) #顯示圖片和三角形的IDcanvas.bind_all('<KeyPress-Up>',moveImage)#綁定方向鍵 upcanvas.bind_all('<KeyPress-Down>',moveImage)canvas.bind_all('<KeyPress-Left>',moveImage)canvas.bind_all('<KeyPress-Right>',moveImage)#canvas.bind_all('<KeyPress-Up>',changeColor)

運行結果：

摁上下左右鍵後可以移動圖片
