如何使用Tkinter按钮来运行Python脚本？

Question

我终于完成了我一直在努力的一个骰子滚动程序，并且我想添加一件最后一件事：我想添加一个说“滚动骰子”的按钮。有没有办法用Tkinter按钮来运行Python脚本？我试过使用：

from tkinter import * 

master = Tk() 

def callback(): 
CODE HERE 

b = Button(master, text="BUTTON TEXT", command=callback) 
b.pack() 

mainloop() 

但是当我使用它时，pygame窗口只是黑色。

我的程序代码是：

exec(open("Dice Crop.py").read(), globals()) 
from pygame.locals import * 
from random import randint 
from tkinter import * 
import pygame 
import sys 

pygame.init() 

font = pygame.font.SysFont("comicsansms",30) 

screen = pygame.display.set_mode((284,177),0,32) 

background = pygame.image.load("background.jpg").convert() 

one = pygame.image.load("one.png").convert_alpha() 
two = pygame.image.load("two.png").convert_alpha() 
three = pygame.image.load("three.png").convert_alpha() 
four = pygame.image.load("four.png").convert_alpha() 
five = pygame.image.load("five.png").convert_alpha() 
six = pygame.image.load("six.png").convert_alpha() 

counter = 0 

while True: 
    for evt in pygame.event.get(): 
     if evt.type == pygame.QUIT: 
      pygame.quit() 
      sys.exit() 

    screen.blit(background,(0, 0)) 

    if counter < 20: 
     n = randint(1,6) 
     counter += 1 

    if n == 1: 
     screen.blit(one,(100,50)) 
     screen.blit(font.render("1",True,(0,200,0)),(125,130)) 
    if n == 2: 
     screen.blit(two,(100,50)) 
     screen.blit(font.render("2",True,(0,200,0)),(125,130)) 
    if n == 3: 
     screen.blit(three,(100,50)) 
     screen.blit(font.render("3",True,(0,200,0)),(125,130)) 
    if n == 4: 
     screen.blit(four,(100,50)) 
     screen.blit(font.render("4",True,(0,200,0)),(125,130)) 
    if n == 5: 
     screen.blit(five,(100,50)) 
     screen.blit(font.render("5",True,(0,200,0)),(125,130)) 
    if n == 6: 
     screen.blit(six,(100,50)) 
     screen.blit(font.render("6",True,(0,200,0)),(125,130)) 
    if counter < 20: 
     print(n) 
    if counter == 20: 
     print(">",n,"<") 


    pygame.time.delay(100) 
    pygame.display.update() 

（所有exec(open("Dice Crop.py").read(), globals())确实是开放的一个Python脚本，需要与多个骰子和切片成单独的图像一个图像）

你可以只使用一个pygame.Rect作为一个按钮。当用户单击鼠标按钮时，Rects有一个collidepoint方法，您可以通过该方法传递鼠标位置。鼠标事件具有pos属性，您可以将该属性传递给collidepoint，或者可以调用pygame.mouse.get_pos()。

from random import randint 
import pygame 
import sys 

pygame.init() 

font = pygame.font.SysFont("comicsansms", 30) 
screen = pygame.display.set_mode((284, 177), 0, 32) 

one = font.render("1", True, (0,200,0)) 
two = font.render("2", True, (0,200,0)) 
three = font.render("3", True, (0,200,0)) 
four = font.render("4", True, (0,200,0)) 
five = font.render("5", True, (0,200,0)) 
six = font.render("6", True, (0,200,0)) 
# Put the images into a list or dictionary to 
# avoid the repetition in the while loop. 
dice = [one, two, three, four, five, six] 

button = pygame.Rect(5, 5, 120, 40) 
button_text = font.render("roll dice", True, (0,200,0)) 
rolling = False 
counter = 0 
n = 0 

while True: 
    for evt in pygame.event.get(): 
     if evt.type == pygame.QUIT: 
      pygame.quit() 
      sys.exit() 
     elif evt.type == pygame.MOUSEBUTTONDOWN: 
      # Check if the mouse clicked on the button. 
      if button.collidepoint(evt.pos): 
       # Start rolling and reset the counter. 
       rolling = True 
       counter = 0 

    if rolling: 
     if counter < 20: 
      n = randint(1,6) 
      counter += 1 
      print(n) 
     elif counter == 20: 
      rolling = False 
      print(">",n,"<") 

    screen.fill((30, 30, 30)) 
    pygame.draw.rect(screen, (70, 80, 90), button) 
    screen.blit(button_text, (button.x+3, button.y-2)) 
    # Blit the current image (index [n-1] of the list). 
    screen.blit(dice[n-1],(100,50)) 

    pygame.time.delay(100) 
    pygame.display.update()
