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)
