title: How to execute a Python program in Tkinter
body: <p>I have a simple Tkinter GUI, with one button and when the button is pushed I want it to run another program that I have written in Python.</p>
  
  <pre><code> def openProgram ():
       #open up MyProgram.py
  
   MGui = Tk()
   MGui.geometry('450x450')
  
   mbutton = Button(text = "Go", command = openProgram).pack()
  </code></pre>
  
  <p>Seems easy enough, maybe I am not searching the correct terms.</p>
