我为重启按钮编写了一个函数，从一开始就启动我的程序。但是我遇到了一个我认为可能特定于MacOS的问题。当我的程序重新启动时，它会在Dock中而不是在屏幕上打开。因此，用户必须单击该程序才能打开它。
我宁愿拥有它，以便程序窗口直接启动到屏幕上。
以下是重启程序的功能：
def restart_program():
python = sys.executable
os.execl(python, python, * sys.argv)
os.system('''/usr/bin/osascript -e 'tell app "Finder" to set frontmost of process "Python" to true' ''')
这是我的完整计划：
from Tkinter import *
from Tkinter import Canvas
import sys
import os
import random
import time
window1 = Tk()
window1.title("Snake")
window1.config(background="black")
window1.geometry("400x400")
coord1 = 0
coord2 = 0
coord3 = 20
coord4 = 20
space_right = 20
space_left = 400
space_up = 400
space_down = 20
score = 0
def restart_program():
python = sys.executable
os.execl(python, python, * sys.argv)
os.system('''/usr/bin/osascript -e 'tell app "Finder" to set frontmost of process "Python" to true' ''')
def quit__window():
quit_window = Toplevel(window1)
quit_window.overrideredirect(1)
quit_window.geometry("230x110+90+50")
quit_window.config(background="black")
canvas2 = Canvas(quit_window, width=230, height=110, bg="black", bd=0, highlightthickness=1, relief="ridge",
highlightbackground="black")
canvas2.pack()
lbl1 = canvas2.create_text(115, 20, text="Game Over!", fill="white", font=("arial bold", 20))
lbl2 = canvas2.create_text(115, 50, text="Your Score: {0}".format(score), fill="white", font=("arial", 20))
restart = Button(canvas2, text="Play Again", highlightbackground="black", command=restart_program)
