在一個窗口中顯示基於輸出的圖像（Python）

Question

我在Python中實現了k-NN算法，該算法返回輸入的類標籤。我需要的是在輸出即將到來時（通過刷新窗口）在一個窗口中顯示分配給類標籤的圖像。問題是，我在GUI編程方面不是很有經驗，因此我需要一些資源和幫助來開始。你可以推薦哪些圖書館，書籍和教程？代碼片斷也將讚賞。

有很多庫允許你添加圖像到你的程序，如Turtle，PIL.ImagTk和Canvas，你甚至可以使用Pygame來獲得最佳性能。

PIL.ImagTk和Canvas：

from Tkinter import * 
from PIL import ImageTk 
backgroundImage = PhotoImage("image path (gif/PPM)") 
canvas = Canvas(width = 200, height = 200, bg = 'blue') 
canvas.pack(expand = YES, fill = BOTH) 

image = ImageTk.PhotoImage(file = "C:/Python27/programas/zimages/gato.png") 
canvas.create_image(10, 10, image = image, anchor = NW) 

mainloop() 

龜：

import turtle 

screen = turtle.Screen() 

# click the image icon in the top right of the code window to see 
# which images are available in this trinket 
image = "rocketship.png" 

# add the shape first then set the turtle shape 
screen.addshape(image) 
turtle.shape(image) 

screen.bgcolor("lightblue") 

move_speed = 10 
turn_speed = 10 

# these defs control the movement of our "turtle" 
def forward(): 
turtle.forward(move_speed) 

def backward(): 
    turtle.backward(move_speed) 

def left(): 
    turtle.left(turn_speed) 

def right(): 
    turtle.right(turn_speed) 

turtle.penup() 
turtle.speed(0) 
turtle.home() 

# now associate the defs from above with certain keyboard events 
screen.onkey(forward, "Up") 
screen.onkey(backward, "Down") 
screen.onkey(left, "Left") 
screen.onkey(right, "Right") 
screen.listen() 

現在，讓我們改變背景

import turtle 

screen = turtle.Screen() 

# this assures that the size of the screen will always be 400x400 ... 
screen.setup(400, 400) 

# ... which is the same size as our image 
# now set the background to our space image 
screen.bgpic("space.jpg") 

# Or, set the shape of a turtle 
screen.addshape("rocketship.png") 
turtle.shape("rocketship.png") 

move_speed = 10 
turn_speed = 10 

# these defs control the movement of our "turtle" 
def forward(): 
    turtle.forward(move_speed) 

def backward(): 
    turtle.backward(move_speed) 

def left(): 
    turtle.left(turn_speed) 

def right(): 
    turtle.right(turn_speed) 

turtle.penup() 
turtle.speed(0) 
turtle.home() 

# now associate the defs from above with certain keyboard events 
screen.onkey(forward, "Up") 
screen.onkey(backward, "Down") 
screen.onkey(left, "Left") 
screen.onkey(right, "Right") 
screen.listen()
