[Geany-Users] Geany on Raspberry Pi... can't see Tkinter window

Hello all!
I have a problem on the Raspberry Pi where Geany will not show the Tkinter window when I am making a simple Python app with tkinter graphics.
I tried asking on Stack Exchange but no luck… I am sorry that I will just paste the question below, it’s the easiest way to be clear about it!
======
My problem: When I run my simple graphics tkinter python script (pasted below) in Geany, it "runs" ... BUT it simply shows the white-text-on-black script window proudly announcing that script completed... while the tkinter graphics window created by the script does not appear! *** When I do this in another IDE, Thonny, the graphics window appears. How do I get Geany to show this script's graphics window correctly? THANKS!
—— below is the code (from a learn-Python book)
from Tkinter import *
window = Tk()
window.title('Alien')
c = Canvas(window, height = 300, width=400)
c.pack()
body=c.create_oval(100,150,300,250,fill='green')
eye=c.create_oval(170,70,230,130,fill='white')
eyeball=c.create_oval(190,90,210,110,fill='black')
mouth=c.create_oval(150,220,250,240,fill='red')
neck=c.create_line(200,150,200,130)
hat=c.create_polygon(180,75,220,75,200,20,fill='blue')
def mouth_open():
c.itemconfig(mouth,fill='black')
def mouth_close():
c.itemconfig(mouth,fill='red')
def blink(event):
c.itemconfig(eye, fill='green')
c.itemconfig(eyeball, state=HIDDEN)
def unblink(event):
c.itemconfig(eye, fill='white')
c.itemconfig(eyeball, state=NORMAL)
words=c.create_text(200,280,text='I am an alien!')
def steal_hat():
c.itemconfig(hat,state=HIDDEN)
c.itemconfig(words, text='Give me my hat back!')
window.attributes('-topmost',1)
def burp(event):
mouth_open()
c.itemconfig(words,text="Burp!")
c.bind_all('<Button-1>', burp)
c.bind_all('<KeyPress-a>',blink)
c.bind_all('<KeyPress-z>',unblink)
def eye_control(event):
key=event.keysym
if key=='Up':
c.move(eyeball,0,-1)
if key=='Down':
c.move(eyeball,0,1)
if key=='Left':
c.move(eyeball,-1,0)
if key=='Right':
c.move(eyeball,1,0)
c.bind_all('<Key>',eye_control)
