Tkinter窗口从命令行打开，但不打开IDE

Question

当我从Windows PowerShell运行此脚本时，将打开tkinter窗口。但是，当我从IDE（Wing IDE 101 6.0）运行脚本时，该脚本将运行并返回，而不会出现任何错误或弹出窗口。如何无需使用powershell弹出tkinter窗口？

import tkinter as tk
from tkinter import *

class MyGame:

    def __init__(self, master):
        self.master = master
        master.title('Stock Market Game')

        self.startGameButton = tk.Button(master, text="Start New Game", command = self.startNewGame)
        self.startGameButton.pack()

        cWidth = 600
        cHeight = 400
        self.canvas = tk.Canvas(master, width = cWidth, height = cHeight)
        self.canvas.create_line(0, cHeight * 1/3, cWidth, cHeight * 1/3)   # coordinates of start and end
        self.canvas.pack()
        self.canvas.bind("Start New Game", self.startNewGame)        

    def startNewGame(self):
        pass


root = Tk()
gui = MyGame(root)
root.mainloop()
